2 Safety information

WARNING

Applicability: Cameras with one or more batteries.

Do not disassemble or do a modification to the battery. The battery contains safety and protection devices which, if damage occurs, can cause the battery to become hot, or cause an explosion or an ignition.

WARNING

Applicability: Cameras with one or more batteries.

If there is a leak from the battery and you get the fluid in your eyes, do not rub your eyes. Flush well with water and immediately get medical care. The battery fluid can cause injury to your eyes if you do not do this.

WARNING

Applicability: Cameras with one or more batteries.

Do not continue to charge the battery if it does not become charged in the specified charging time. If you continue to charge the battery, it can become hot and cause an explosion or ignition. Injury to persons can occur.

WARNING

Applicability: Cameras with one or more batteries.

Only use the correct equipment to remove the electrical power from the battery. If you do not use the correct equipment, you can decrease the performance or the life cycle of the battery. If you do not use the correct equipment, an incorrect flow of current to the battery can occur. This can cause the battery to become hot, or cause an explosion. Injury to persons can occur.

WARNING

Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on containers before you use a liquid. The liquids can be dangerous. Injury to persons can occur.

CAUTION

Do not point the infrared camera (with or without the lens cover) at strong energy sources, for example, devices that cause laser radiation, or the sun. This can have an unwanted effect on the accuracy of the camera. It can also cause damage to the detector in the camera.

7.13 Changing image mode

7.13.1

General

The camera can operate in five different image modes:

• Thermal MSX (Multi Spectral Dynamic Imaging): The camera displays an infrared image where the edges of the objects are enhanced.

#T559828; r.18043/22369; en-US

7 Operation

• Thermal: The camera displays a fully thermal image.

• Picture-in-picture: The camera displays a digital camera image with a superimposed infrared image frame.

• Thermal blending: The camera displays a blended image that uses a mix of infrared pixels and digital photo pixels. The mixing level can be adjusted.

• Digital camera: The camera displays a digital camera image.

#T559828; r.18043/22369; en-US

7 Operation

To display a good fusion image (Thermal MSX, Picture-in-picture, and Thermal blending modes), the camera must make adjustments to compensate for the small difference in position between the digital camera lens and the infrared lens. To adjust the image accurately, the camera requires the alignment distance (i.e., the distance to the object).

7.13.2

Procedure

Follow this procedure:

1. Push the center of the navigation pad. This displays a toolbar.

2. On the toolbar, select Image mode . This displays a toolbar.

3. On the toolbar, select one of the following:

• Thermal MSX .

• Thermal .

• Picture-in-picture .

• Thermal blending . This displays a dialog box where you can select the mixing level.

• Digital camera .

4. If you have selected the Thermal MSX, Picture-in-picture, or Thermal blending mode, also set the distance to the object by doing the following:

• On the Image mode toolbar, select Alignment distance . This displays a dialog box.

• In the dialog box, select the distance to the object.

7.14 Changing the temperature scale mode

7.14.1

General

The camera can, depending on the camera model, operate in different temperature scale modes:

• Auto mode: In this mode, the camera is continuously auto-adjusted for the best image brightness and contrast.

• Lock mode: In this mode, the camera locks the temperature span and the temperature level.

• Manual mode: This mode allows manual adjustments of the temperature span and the temperature level.

7.14.2

When to use Lock mode

A typical situation where you would want to use Lock mode is when looking for temperature anomalies in two items with a similar design or construction.

#T559828; r.18043/22369; en-US

7 Operation

For example, if you are looking at two cables, where you suspect one is overheated, working in Lock mode will clearly show that one is overheated. The higher temperature in that cable would create a lighter color for the higher temperature.

If you use Auto mode instead, the color for the two items will appear the same.

7.14.3

When to use Manual mode

7.14.3.1

Example 1

This figure shows two infrared images of cable connection points. In the left image, a correct analysis of the circled cable is difficult if you only auto-adjust the image. You can analyze this cable in more detail if you:

• Change the temperature scale maximum limit.

• Change the temperature scale minimum limit.

• Change the temperature scale maximum and minimum limits.

In the left image, the image is auto-adjusted. In the right image, the maximum and minimum temperature levels have been changed to temperature levels near the object. On the temperature scale to the right of each image you can see how the temperature levels were changed.

7.14.3.2

Example 2

This figure shows two infrared images of an isolator in a power line.

In the left image, the cold sky and the power line structure are recorded at a minimum temperature of –26.0°C (–14.8°F). In the right image, the maximum and minimum temperature levels have been changed to temperature levels near the isolator. This makes it easier to analyze the temperature variations in the isolator.

7.14.4

Procedure

Follow this procedure:

1. Push the center of the navigation pad. This displays a toolbar.

#T559828; r.18043/22369; en-US

7 Operation

2. On the toolbar, select Temperature scale . This displays a toolbar.

3. On the toolbar, select one of the following:

• Auto .

6. In the list, select the material.

7.17 Changing the emissivity as a custom value

7.17.1

General

For very precise measurements, you may need to set the emissivity, instead of selecting a surface property or a custom material. You also need to understand how emissivity and reflectivity affect measurements, rather than just simply selecting a surface property.

Emissivity is a property that indicates how much radiation originates from an object as opposed to being reflected by it. A lower value indicates that a larger proportion is being reflected, while a high value indicates that a lower proportion is being reflected.

Polished stainless steel, for example, has an emissivity of 0.14, while a structured PVC floor typically has an emissivity of 0.93.

For more information about emissivity, see section 15 Thermographic measurement tech-

niques, page 54.

7.18 Changing the reflected apparent temperature

7.18.1

General

This parameter is used to compensate for the radiation reflected by the object. If the emissivity is low and the object temperature significantly different from that of the reflected temperature, it will be important to set and compensate for the reflected apparent temperature correctly.

For more information about reflected apparent temperature, see section 15 Thermo-

graphic measurement techniques, page 54.

12 Application examples

12.1 Moisture & water damage

12.1.1

General

It is often possible to detect moisture and water damage in a house by using an infrared camera. This is partly because the damaged area has a different heat conduction property and partly because it has a different thermal capacity to store heat than the surrounding material.

NOTE

Many factors can come into play as to how moisture or water damage will appear in an infrared image.

For example, heating and cooling of these parts takes place at different rates depending on the material and the time of day. For this reason, it is important that other methods are used as well to check for moisture or water damage.

12.1.2

Figure

The image below shows extensive water damage on an external wall where the water has penetrated the outer facing because of an incorrectly installed window ledge.

12.2 Faulty contact in socket

12.2.1

General

Depending on the type of connection a socket has, an improperly connected wire can result in local temperature increase. This temperature increase is caused by the reduced contact area between the connection point of the incoming wire and the socket , and can result in an electrical fire.

NOTE

A socket’s construction may differ dramatically from one manufacturer to another. For this reason, different faults in a socket can lead to the same typical appearance in an infrared image.

Local temperature increase can also result from improper contact between wire and socket, or from difference in load.

#T559828; r.18043/22369; en-US

12 Application examples

12.2.2

Figure

The image below shows a connection of a cable to a socket where improper contact in the connection has resulted in local temperature increase.

12.3 Oxidized socket

12.3.1

General

Depending on the type of socket and the environment in which the socket is installed, oxides may occur on the socket's contact surfaces. These oxides can lead to locally increased resistance when the socket is loaded, which can be seen in an infrared image as local temperature increase.

NOTE

A socket’s construction may differ dramatically from one manufacturer to another. For this reason, different faults in a socket can lead to the same typical appearance in an infrared image.

Local temperature increase can also result from improper contact between a wire and socket, or from difference in load.

12.3.2

Figure

The image below shows a series of fuses where one fuse has a raised temperature on the contact surfaces against the fuse holder. Because of the fuse holder’s blank metal, the temperature increase is not visible there, while it is visible on the fuse’s ceramic material.

#T559828; r.18043/22369; en-US

12 Application examples

12.4 Insulation deficiencies

12.4.1

General

Insulation deficiencies may result from insulation losing volume over the course of time and thereby not entirely filling the cavity in a frame wall.

An infrared camera allows you to see these insulation deficiencies because they either have a different heat conduction property than sections with correctly installed insulation, and/or show the area where air is penetrating the frame of the building.

NOTE

When you are inspecting a building, the temperature difference between the inside and outside should be at least 10°C (18°F). Studs, water pipes, concrete columns, and similar components may resemble an insulation deficiency in an infrared image. Minor differences may also occur naturally.

12.4.2

Figure

In the image below, insulation in the roof framing is lacking. Due to the absence of insulation, air has forced its way into the roof structure, which thus takes on a different characteristic appearance in the infrared image.

#T559828; r.18043/22369; en-US

12 Application examples

12.5 Draft

12.5.1

General

Draft can be found under baseboards, around door and window casings, and above ceiling trim. This type of draft is often possible to see with an infrared camera, as a cooler airstream cools down the surrounding surface.

NOTE

When you are investigating draft in a house, there should be sub-atmospheric pressure in the house.

Close all doors, windows, and ventilation ducts, and allow the kitchen fan to run for a while before you take the infrared images.

An infrared image of draft often shows a typical stream pattern. You can see this stream pattern clearly in the picture below.

Also keep in mind that drafts can be concealed by heat from floor heating circuits.

12.5.2

Figure

The image below shows a ceiling hatch where faulty installation has resulted in a strong draft.

15 Thermographic measurement techniques

15.1 Introduction

An infrared camera measures and images the emitted infrared radiation from an object.

The fact that radiation is a function of object surface temperature makes it possible for the camera to calculate and display this temperature.

However, the radiation measured by the camera does not only depend on the temperature of the object but is also a function of the emissivity. Radiation also originates from the surroundings and is reflected in the object. The radiation from the object and the reflected radiation will also be influenced by the absorption of the atmosphere.

To measure temperature accurately, it is therefore necessary to compensate for the effects of a number of different radiation sources. This is done on-line automatically by the camera. The following object parameters must, however, be supplied for the camera:

• The emissivity of the object

• The reflected apparent temperature

• The distance between the object and the camera

• The relative humidity

• Temperature of the atmosphere

15.2 Emissivity

The most important object parameter to set correctly is the emissivity which, in short, is a measure of how much radiation is emitted from the object, compared to that from a perfect blackbody of the same temperature.

Normally, object materials and surface treatments exhibit emissivity ranging from approximately 0.1 to 0.95. A highly polished (mirror) surface falls below 0.1, while an oxidized or painted surface has a higher emissivity. Oil-based paint, regardless of color in the visible spectrum, has an emissivity over 0.9 in the infrared. Human skin exhibits an emissivity

0.97 to 0.98.

Non-oxidized metals represent an extreme case of perfect opacity and high reflexivity, which does not vary greatly with wavelength. Consequently, the emissivity of metals is low

– only increasing with temperature. For non-metals, emissivity tends to be high, and decreases with temperature.

15.2.1

Finding the emissivity of a sample

15.2.1.1

Step 1: Determining reflected apparent temperature

Use one of the following two methods to determine reflected apparent temperature:

#T559828; r.18043/22369; en-US

15 Thermographic measurement techniques

15.2.1.1.1

Method 1: Direct method

Follow this procedure:

1. Look for possible reflection sources, considering that the incident angle = reflection angle (a = b).

Figure 15.1 1 = Reflection source

2. If the reflection source is a spot source, modify the source by obstructing it using a piece if cardboard.

Figure 15.2 1 = Reflection source

#T559828; r.18043/22369; en-US

15 Thermographic measurement techniques

3. Measure the radiation intensity (= apparent temperature) from the reflecting source using the following settings:

• Emissivity: 1.0

• D obj

: 0

You can measure the radiation intensity using one of the following two methods:

Figure 15.3 1 = Reflection source

NOTE

Using a thermocouple to measure reflected apparent temperature is not recommended for two important reasons:

• A thermocouple does not measure radiation intensity

• A thermocouple requires a very good thermal contact to the surface, usually by gluing and covering the sensor by a thermal isolator.

15.2.1.1.2

Method 2: Reflector method

Follow this procedure:

1. Crumble up a large piece of aluminum foil.

2. Uncrumble the aluminum foil and attach it to a piece of cardboard of the same size.

3. Put the piece of cardboard in front of the object you want to measure. Make sure that the side with aluminum foil points to the camera.

4. Set the emissivity to 1.0.

#T559828; r.18043/22369; en-US

15 Thermographic measurement techniques

5. Measure the apparent temperature of the aluminum foil and write it down.

Figure 15.4 Measuring the apparent temperature of the aluminum foil.

15.2.1.2

Step 2: Determining the emissivity

Follow this procedure:

1. Select a place to put the sample.

2. Determine and set reflected apparent temperature according to the previous procedure.

3. Put a piece of electrical tape with known high emissivity on the sample.

4. Heat the sample at least 20 K above room temperature. Heating must be reasonably even.

5. Focus and auto-adjust the camera, and freeze the image.

6. Adjust Level and Span for best image brightness and contrast.

7. Set emissivity to that of the tape (usually 0.97).

8. Measure the temperature of the tape using one of the following measurement functions:

• Isotherm (helps you to determine both the temperature and how evenly you have heated the sample)

• Spot (simpler)

• Box Avg (good for surfaces with varying emissivity).

9. Write down the temperature.

10. Move your measurement function to the sample surface.

11. Change the emissivity setting until you read the same temperature as your previous measurement.

12. Write down the emissivity.

NOTE

• Avoid forced convection

• Look for a thermally stable surrounding that will not generate spot reflections

• Use high quality tape that you know is not transparent, and has a high emissivity you are certain of

• This method assumes that the temperature of your tape and the sample surface are the same. If they are not, your emissivity measurement will be wrong.

#T559828; r.18043/22369; en-US

15 Thermographic measurement techniques

15.3 Reflected apparent temperature

This parameter is used to compensate for the radiation reflected in the object. If the emissivity is low and the object temperature relatively far from that of the reflected it will be important to set and compensate for the reflected apparent temperature correctly.

15.4 Distance

The distance is the distance between the object and the front lens of the camera. This parameter is used to compensate for the following two facts:

• That radiation from the target is absorbed by the atmosphere between the object and the camera.

• That radiation from the atmosphere itself is detected by the camera.

15.5 Relative humidity

The camera can also compensate for the fact that the transmittance is also dependent on the relative humidity of the atmosphere. To do this set the relative humidity to the correct value. For short distances and normal humidity the relative humidity can normally be left at a default value of 50%.

15.6 Other parameters

In addition, some cameras and analysis programs from FLIR Systems allow you to compensate for the following parameters:

• Atmospheric temperature – i.e. the temperature of the atmosphere between the camera and the target

• External optics temperature – i.e. the temperature of any external lenses or windows used in front of the camera

• External optics transmittance – i.e. the transmission of any external lenses or windows used in front of the camera

16 History of infrared technology

Before the year 1800, the existence of the infrared portion of the electromagnetic spectrum wasn't even suspected. The original significance of the infrared spectrum, or simply ‘the infrared’ as it is often called, as a form of heat radiation is perhaps less obvious today than it was at the time of its discovery by Herschel in 1800.

Figure 16.1 Sir William Herschel (1738–1822)

The discovery was made accidentally during the search for a new optical material. Sir William Herschel – Royal Astronomer to King George III of England, and already famous for his discovery of the planet Uranus – was searching for an optical filter material to reduce the brightness of the sun’s image in telescopes during solar observations. While testing different samples of colored glass which gave similar reductions in brightness he was intrigued to find that some of the samples passed very little of the sun’s heat, while others passed so much heat that he risked eye damage after only a few seconds’ observation.

Herschel was soon convinced of the necessity of setting up a systematic experiment, with the objective of finding a single material that would give the desired reduction in brightness as well as the maximum reduction in heat. He began the experiment by actually repeating

Newton’s prism experiment, but looking for the heating effect rather than the visual distribution of intensity in the spectrum. He first blackened the bulb of a sensitive mercury-inglass thermometer with ink, and with this as his radiation detector he proceeded to test the heating effect of the various colors of the spectrum formed on the top of a table by passing sunlight through a glass prism. Other thermometers, placed outside the sun’s rays, served as controls.

As the blackened thermometer was moved slowly along the colors of the spectrum, the temperature readings showed a steady increase from the violet end to the red end. This was not entirely unexpected, since the Italian researcher, Landriani, in a similar experiment in 1777 had observed much the same effect. It was Herschel, however, who was the first to recognize that there must be a point where the heating effect reaches a maximum, and that measurements confined to the visible portion of the spectrum failed to locate this point.

Figure 16.2 Marsilio Landriani (1746–1815)

#T559828; r.18043/22369; en-US

16 History of infrared technology

Moving the thermometer into the dark region beyond the red end of the spectrum, Herschel confirmed that the heating continued to increase. The maximum point, when he found it, lay well beyond the red end – in what is known today as the ‘infrared wavelengths’.

When Herschel revealed his discovery, he referred to this new portion of the electromagnetic spectrum as the ‘thermometrical spectrum’. The radiation itself he sometimes referred to as ‘dark heat’, or simply ‘the invisible rays’. Ironically, and contrary to popular opinion, it wasn't Herschel who originated the term ‘infrared’. The word only began to appear in print around 75 years later, and it is still unclear who should receive credit as the originator.

Herschel’s use of glass in the prism of his original experiment led to some early controversies with his contemporaries about the actual existence of the infrared wavelengths. Different investigators, in attempting to confirm his work, used various types of glass indiscriminately, having different transparencies in the infrared. Through his later experiments, Herschel was aware of the limited transparency of glass to the newly-discovered thermal radiation, and he was forced to conclude that optics for the infrared would probably be doomed to the use of reflective elements exclusively (i.e. plane and curved mirrors). Fortunately, this proved to be true only until 1830, when the Italian investigator,

Melloni, made his great discovery that naturally occurring rock salt (NaCl) – which was available in large enough natural crystals to be made into lenses and prisms – is remarkably transparent to the infrared. The result was that rock salt became the principal infrared optical material, and remained so for the next hundred years, until the art of synthetic crystal growing was mastered in the 1930’s.

Figure 16.3 Macedonio Melloni (1798–1854)

Thermometers, as radiation detectors, remained unchallenged until 1829, the year Nobili invented the thermocouple. (Herschel’s own thermometer could be read to 0.2 °C (0.036 °

F), and later models were able to be read to 0.05 °C (0.09 °F)). Then a breakthrough occurred; Melloni connected a number of thermocouples in series to form the first thermopile.

The new device was at least 40 times as sensitive as the best thermometer of the day for detecting heat radiation – capable of detecting the heat from a person standing three meters away.

The first so-called ‘heat-picture’ became possible in 1840, the result of work by Sir John

Herschel, son of the discoverer of the infrared and a famous astronomer in his own right.

Based upon the differential evaporation of a thin film of oil when exposed to a heat pattern focused upon it, the thermal image could be seen by reflected light where the interference effects of the oil film made the image visible to the eye. Sir John also managed to obtain a primitive record of the thermal image on paper, which he called a ‘thermograph’.

#T559828; r.18043/22369; en-US

16 History of infrared technology

Figure 16.4 Samuel P. Langley (1834–1906)

The improvement of infrared-detector sensitivity progressed slowly. Another major breakthrough, made by Langley in 1880, was the invention of the bolometer. This consisted of a thin blackened strip of platinum connected in one arm of a Wheatstone bridge circuit upon which the infrared radiation was focused and to which a sensitive galvanometer responded. This instrument is said to have been able to detect the heat from a cow at a distance of 400 meters.

An English scientist, Sir James Dewar, first introduced the use of liquefied gases as cooling agents (such as liquid nitrogen with a temperature of -196 °C (-320.8 °F)) in low temperature research. In 1892 he invented a unique vacuum insulating container in which it is possible to store liquefied gases for entire days. The common ‘thermos bottle’, used for storing hot and cold drinks, is based upon his invention.

Between the years 1900 and 1920, the inventors of the world ‘discovered’ the infrared.

Many patents were issued for devices to detect personnel, artillery, aircraft, ships – and even icebergs. The first operating systems, in the modern sense, began to be developed during the 1914–18 war, when both sides had research programs devoted to the military exploitation of the infrared. These programs included experimental systems for enemy intrusion/detection, remote temperature sensing, secure communications, and ‘flying torpedo’ guidance. An infrared search system tested during this period was able to detect an approaching airplane at a distance of 1.5 km (0.94 miles), or a person more than 300 meters (984 ft.) away.

The most sensitive systems up to this time were all based upon variations of the bolometer idea, but the period between the two wars saw the development of two revolutionary new infrared detectors: the image converter and the photon detector. At first, the image converter received the greatest attention by the military, because it enabled an observer for the first time in history to literally ‘see in the dark’. However, the sensitivity of the image converter was limited to the near infrared wavelengths, and the most interesting military targets (i.e. enemy soldiers) had to be illuminated by infrared search beams. Since this involved the risk of giving away the observer’s position to a similarly-equipped enemy observer, it is understandable that military interest in the image converter eventually faded.

The tactical military disadvantages of so-called 'active’ (i.e. search beam-equipped) thermal imaging systems provided impetus following the 1939–45 war for extensive secret military infrared-research programs into the possibilities of developing ‘passive’ (no search beam) systems around the extremely sensitive photon detector. During this period, military secrecy regulations completely prevented disclosure of the status of infrared-imaging technology. This secrecy only began to be lifted in the middle of the 1950’s, and from that time adequate thermal-imaging devices finally began to be available to civilian science and industry.

17 Theory of thermography

17.1 Introduction

The subjects of infrared radiation and the related technique of thermography are still new to many who will use an infrared camera. In this section the theory behind thermography will be given.

17.2 The electromagnetic spectrum

The electromagnetic spectrum is divided arbitrarily into a number of wavelength regions, called bands, distinguished by the methods used to produce and detect the radiation.

There is no fundamental difference between radiation in the different bands of the electromagnetic spectrum. They are all governed by the same laws and the only differences are those due to differences in wavelength.

Figure 17.1 The electromagnetic spectrum. 1: X-ray; 2: UV; 3: Visible; 4: IR; 5: Microwaves; 6: Radiowaves.

Thermography makes use of the infrared spectral band. At the short-wavelength end the boundary lies at the limit of visual perception, in the deep red. At the long-wavelength end it merges with the microwave radio wavelengths, in the millimeter range.

The infrared band is often further subdivided into four smaller bands, the boundaries of which are also arbitrarily chosen. They include: the near infrared (0.75–3 μm), the middle

infrared (3–6 μm), the far infrared (6–15 μm) and the extreme infrared (15–100 μm).

Although the wavelengths are given in μm (micrometers), other units are often still used to measure wavelength in this spectral region, e.g. nanometer (nm) and Ångström (Å).

The relationships between the different wavelength measurements is:

17.3 Blackbody radiation

A blackbody is defined as an object which absorbs all radiation that impinges on it at any wavelength. The apparent misnomer black relating to an object emitting radiation is explained by Kirchhoff’s Law (after Gustav Robert Kirchhoff, 1824–1887), which states that a body capable of absorbing all radiation at any wavelength is equally capable in the emission of radiation.

#T559828; r.18043/22369; en-US

17 Theory of thermography

Figure 17.2 Gustav Robert Kirchhoff (1824–1887)

The construction of a blackbody source is, in principle, very simple. The radiation characteristics of an aperture in an isotherm cavity made of an opaque absorbing material represents almost exactly the properties of a blackbody. A practical application of the principle to the construction of a perfect absorber of radiation consists of a box that is light tight except for an aperture in one of the sides. Any radiation which then enters the hole is scattered and absorbed by repeated reflections so only an infinitesimal fraction can possibly escape. The blackness which is obtained at the aperture is nearly equal to a blackbody and almost perfect for all wavelengths.

By providing such an isothermal cavity with a suitable heater it becomes what is termed a

cavity radiator. An isothermal cavity heated to a uniform temperature generates blackbody radiation, the characteristics of which are determined solely by the temperature of the cavity. Such cavity radiators are commonly used as sources of radiation in temperature reference standards in the laboratory for calibrating thermographic instruments, such as a

FLIR Systems camera for example.

If the temperature of blackbody radiation increases to more than 525°C (977°F), the source begins to be visible so that it appears to the eye no longer black. This is the incipient red heat temperature of the radiator, which then becomes orange or yellow as the temperature increases further. In fact, the definition of the so-called color temperature of an object is the temperature to which a blackbody would have to be heated to have the same appearance.

Now consider three expressions that describe the radiation emitted from a blackbody.

17.3.1

Planck’s law

Figure 17.3 Max Planck (1858–1947)

Max Planck (1858–1947) was able to describe the spectral distribution of the radiation from a blackbody by means of the following formula:

#T559828; r.18043/22369; en-US

17 Theory of thermography

h k

λ where:

λb c

Blackbody spectral radiant emittance at wavelength λ.

Velocity of light = 3 × 10 8 m/s

Planck’s constant = 6.6 × 10 -34 Joule sec.

Boltzmann’s constant = 1.4 × 10 -23 Joule/K.

Absolute temperature (K) of a blackbody.

Wavelength (μm).

NOTE

The factor 10 -6 is used since spectral emittance in the curves is expressed in Watt/m 2 , μm.

Planck’s formula, when plotted graphically for various temperatures, produces a family of curves. Following any particular Planck curve, the spectral emittance is zero at λ = 0, then increases rapidly to a maximum at a wavelength λ max and after passing it approaches zero again at very long wavelengths. The higher the temperature, the shorter the wavelength at which maximum occurs.

Figure 17.4 Blackbody spectral radiant emittance according to Planck’s law, plotted for various absolute temperatures. 1: Spectral radiant emittance (W/cm

× 10

(μm)); 2: Wavelength (μm)

17.3.2

Wien’s displacement law

By differentiating Planck’s formula with respect to λ, and finding the maximum, we have:

#T559828; r.18043/22369; en-US

17 Theory of thermography

This is Wien’s formula (after Wilhelm Wien, 1864–1928), which expresses mathematically the common observation that colors vary from red to orange or yellow as the temperature of a thermal radiator increases. The wavelength of the color is the same as the wavelength calculated for λ max

. A good approximation of the value of λ max for a given blackbody temperature is obtained by applying the rule-of-thumb 3 000/T μm. Thus, a very hot star such as Sirius (11 000 K), emitting bluish-white light, radiates with the peak of spectral radiant emittance occurring within the invisible ultraviolet spectrum, at wavelength 0.27 μm.

Figure 17.5 Wilhelm Wien (1864–1928)

The sun (approx. 6 000 K) emits yellow light, peaking at about 0.5 μm in the middle of the visible light spectrum.

At room temperature (300 K) the peak of radiant emittance lies at 9.7 μm, in the far infrared, while at the temperature of liquid nitrogen (77 K) the maximum of the almost insignificant amount of radiant emittance occurs at 38 μm, in the extreme infrared wavelengths.

#T559828; r.18043/22369; en-US

17 Theory of thermography

17.3.3

Stefan-Boltzmann's law

By integrating Planck’s formula from λ = 0 to λ = ∞, we obtain the total radiant emittance

(W b

) of a blackbody:

This is the Stefan-Boltzmann formula (after Josef Stefan, 1835–1893, and Ludwig Boltz-

mann, 1844–1906), which states that the total emissive power of a blackbody is proportional to the fourth power of its absolute temperature. Graphically, W b represents the area below the Planck curve for a particular temperature. It can be shown that the radiant emittance in the interval λ = 0 to λ max is only 25% of the total, which represents about the amount of the sun’s radiation which lies inside the visible light spectrum.

Figure 17.7 Josef Stefan (1835–1893), and Ludwig Boltzmann (1844–1906)

Using the Stefan-Boltzmann formula to calculate the power radiated by the human body, at a temperature of 300 K and an external surface area of approx. 2 m 2 , we obtain 1 kW.

This power loss could not be sustained if it were not for the compensating absorption of radiation from surrounding surfaces, at room temperatures which do not vary too drastically from the temperature of the body – or, of course, the addition of clothing.

17.3.4

Non-blackbody emitters

So far, only blackbody radiators and blackbody radiation have been discussed. However, real objects almost never comply with these laws over an extended wavelength region – although they may approach the blackbody behavior in certain spectral intervals. For example, a certain type of white paint may appear perfectly white in the visible light spectrum, but becomes distinctly gray at about 2 μm, and beyond 3 μm it is almost black.

There are three processes which can occur that prevent a real object from acting like a blackbody: a fraction of the incident radiation α may be absorbed, a fraction ρ may be reflected, and a fraction τ may be transmitted. Since all of these factors are more or less wavelength dependent, the subscript λ is used to imply the spectral dependence of their definitions. Thus:

• The spectral absorptance α

= the ratio of the spectral radiant power absorbed by an object to that incident upon it.

• The spectral reflectance ρ

= the ratio of the spectral radiant power reflected by an object to that incident upon it.

• The spectral transmittance τ

= the ratio of the spectral radiant power transmitted through an object to that incident upon it.

The sum of these three factors must always add up to the whole at any wavelength, so we have the relation:

For opaque materials τ

= 0 and the relation simplifies to:

#T559828; r.18043/22369; en-US

17 Theory of thermography

Another factor, called the emissivity, is required to describe the fraction ε of the radiant emittance of a blackbody produced by an object at a specific temperature. Thus, we have the definition:

The spectral emissivity ε

= the ratio of the spectral radiant power from an object to that from a blackbody at the same temperature and wavelength.

Expressed mathematically, this can be written as the ratio of the spectral emittance of the object to that of a blackbody as follows:

Generally speaking, there are three types of radiation source, distinguished by the ways in which the spectral emittance of each varies with wavelength.

• A blackbody, for which ε

= ε = 1

• A graybody, for which ε

= ε = constant less than 1

• A selective radiator, for which ε varies with wavelength

According to Kirchhoff’s law, for any material the spectral emissivity and spectral absorptance of a body are equal at any specified temperature and wavelength. That is:

From this we obtain, for an opaque material (since α

+ ρ

= 1):

For highly polished materials ε

λ approaches zero, so that for a perfectly reflecting material

(i.e. a perfect mirror) we have:

For a graybody radiator, the Stefan-Boltzmann formula becomes:

This states that the total emissive power of a graybody is the same as a blackbody at the same temperature reduced in proportion to the value of ε from the graybody.

17.4 Infrared semi-transparent materials

Consider now a non-metallic, semi-transparent body – let us say, in the form of a thick flat plate of plastic material. When the plate is heated, radiation generated within its volume must work its way toward the surfaces through the material in which it is partially absorbed.

Moreover, when it arrives at the surface, some of it is reflected back into the interior. The back-reflected radiation is again partially absorbed, but some of it arrives at the other surface, through which most of it escapes; part of it is reflected back again. Although the progressive reflections become weaker and weaker they must all be added up when the total emittance of the plate is sought. When the resulting geometrical series is summed, the effective emissivity of a semi-transparent plate is obtained as:

#T559828; r.18043/22369; en-US

17 Theory of thermography

When the plate becomes opaque this formula is reduced to the single formula:

This last relation is a particularly convenient one, because it is often easier to measure reflectance than to measure emissivity directly.

#T559828; r.18043/22369; en-US

18 The measurement formula

As already mentioned, when viewing an object, the camera receives radiation not only from the object itself. It also collects radiation from the surroundings reflected via the object surface. Both these radiation contributions become attenuated to some extent by the atmosphere in the measurement path. To this comes a third radiation contribution from the atmosphere itself.

This description of the measurement situation, as illustrated in the figure below, is so far a fairly true description of the real conditions. What has been neglected could for instance be sun light scattering in the atmosphere or stray radiation from intense radiation sources outside the field of view. Such disturbances are difficult to quantify, however, in most cases they are fortunately small enough to be neglected. In case they are not negligible, the measurement configuration is likely to be such that the risk for disturbance is obvious, at least to a trained operator. It is then his responsibility to modify the measurement situation to avoid the disturbance e.g. by changing the viewing direction, shielding off intense radiation sources etc.

Accepting the description above, we can use the figure below to derive a formula for the calculation of the object temperature from the calibrated camera output.

Figure 18.1 A schematic representation of the general thermographic measurement situation.1: Surroundings; 2: Object; 3: Atmosphere; 4: Camera

Assume that the received radiation power W from a blackbody source of temperature

T source on short distance generates a camera output signal U source that is proportional to the power input (power linear camera). We can then write (Equation 1): or, with simplified notation: where C is a constant.

Should the source be a graybody with emittance ε, the received radiation would consequently be εW source

We are now ready to write the three collected radiation power terms:

1. Emission from the object = ετW obj

, where ε is the emittance of the object and τ is the transmittance of the atmosphere. The object temperature is T obj

#T559828; r.18043/22369; en-US

18 The measurement formula

2. Reflected emission from ambient sources = (1 – ε)τW refl

, where (1 – ε) is the reflectance of the object. The ambient sources have the temperature T refl

It has here been assumed that the temperature T refl is the same for all emitting surfaces within the halfsphere seen from a point on the object surface. This is of course sometimes a simplification of the true situation. It is, however, a necessary simplification in order to derive a workable formula, and T refl can – at least theoretically – be given a value that represents an efficient temperature of a complex surrounding.

Note also that we have assumed that the emittance for the surroundings = 1. This is correct in accordance with Kirchhoff’s law: All radiation impinging on the surrounding surfaces will eventually be absorbed by the same surfaces. Thus the emittance = 1.

(Note though that the latest discussion requires the complete sphere around the object to be considered.)

3. Emission from the atmosphere = (1 – τ)τW atm

, where (1 – τ) is the emittance of the atmosphere. The temperature of the atmosphere is T atm

The total received radiation power can now be written (Equation 2):

We multiply each term by the constant C of Equation 1 and replace the CW products by the corresponding U according to the same equation, and get (Equation 3):

Solve Equation 3 for U obj

(Equation 4):

This is the general measurement formula used in all the FLIR Systems thermographic equipment. The voltages of the formula are:

The operator has to supply a number of parameter values for the calculation:

• the object emittance ε,

• the relative humidity,

• T atm

• object distance (D obj

)

• the (effective) temperature of the object surroundings, or the reflected ambient temperature T refl

, and

• the temperature of the atmosphere T atm

This task could sometimes be a heavy burden for the operator since there are normally no easy ways to find accurate values of emittance and atmospheric transmittance for the

#T559828; r.18043/22369; en-US

18 The measurement formula

actual case. The two temperatures are normally less of a problem provided the surroundings do not contain large and intense radiation sources.

A natural question in this connection is: How important is it to know the right values of these parameters? It could though be of interest to get a feeling for this problem already here by looking into some different measurement cases and compare the relative magnitudes of the three radiation terms. This will give indications about when it is important to use correct values of which parameters.

The figures below illustrates the relative magnitudes of the three radiation contributions for three different object temperatures, two emittances, and two spectral ranges: SW and LW.

Remaining parameters have the following fixed values:

• τ = 0.88

• T refl

= +20°C (+68°F)

• T atm

= +20°C (+68°F)

It is obvious that measurement of low object temperatures are more critical than measuring high temperatures since the ‘disturbing’ radiation sources are relatively much stronger in the first case. Should also the object emittance be low, the situation would be still more difficult.

We have finally to answer a question about the importance of being allowed to use the calibration curve above the highest calibration point, what we call extrapolation. Imagine that we in a certain case measure U tot

= 4.5 volts. The highest calibration point for the camera was in the order of 4.1 volts, a value unknown to the operator. Thus, even if the object happened to be a blackbody, i.e. U obj

= U tot

, we are actually performing extrapolation of the calibration curve when converting 4.5 volts into temperature.

Let us now assume that the object is not black, it has an emittance of 0.75, and the transmittance is 0.92. We also assume that the two second terms of Equation 4 amount to 0.5

volts together. Computation of U obj by means of Equation 4 then results in U obj

= 4.5 / 0.75

/ 0.92 – 0.5 = 6.0. This is a rather extreme extrapolation, particularly when considering that the video amplifier might limit the output to 5 volts! Note, though, that the application of the calibration curve is a theoretical procedure where no electronic or other limitations exist.

We trust that if there had been no signal limitations in the camera, and if it had been calibrated far beyond 5 volts, the resulting curve would have been very much the same as our real curve extrapolated beyond 4.1 volts, provided the calibration algorithm is based on radiation physics, like the FLIR Systems algorithm. Of course there must be a limit to such extrapolations.
