Introducing the SK8160CKO-LB Line Scan Camera

1.1
Introducing the SK8160CKO-LB Line Scan Camera
Intended Purpose and Overview
The SK line scan camera series is designed for a wide
range of vision and inspection applications in both industrial and scientific environments. The SK8160CKO-LB is
compliant with CameraLink Specification Rev 1.1.
Data acquisition requires that the grabber board conforms
to the CameraLinkTM standard. The grabber board
provides the Start-Of-Scan (SOS) signals and thereby
determines the exposure time and line frequency of the
camera.
CameraLink reads the camera specifications from configuration files. Prior to the iniatial start-up, the appropriate
camera specific file must be created for the grabber in
use.
Beyond, the configuration program SkCLConfig allows
the full parameterization of the camera settings, such as
gain, offset and pixel frequency, via the CameraLinkTM
serial port interface. SkCLConfig uses the clser*.dll driver
that is supplied with the CameraLink grabber board.
Normally, functions like Shading Correction, signal
modification with a look-up table (LUT) or the definition of
a region of interest (ROI) are implemented in the grabber
board. For special requirements these functions can be
made availabel within the camera, please contact the
Schäfter + Kirchhoff customer support where appropriate.
The camera is supplied precalibrated, with factory
settings for gain and offset. A readjustment is normally
not necessary.
The successful use of the line scan camera requires that
the complete optical system is properly set up, especially
the location of the illumination, the degree of focus of the
lens and the aperture setting. The most critical factor is
the perpendicular alignment of the sensor axis either with
the object to be measured or the direction of its relative
travel when scanned. For further guidance see section
Adjustments for Optimum Scan Results, p. 16.
For the development of custom applications use the
software development kits released from the grabber
board producers.

•
The best fixing point of the camera is the collar for
the mounting bracket SK5105-L (available as an
accessory).
•
•
Four threaded holes M3 x 6.5 mm provide further
options for customized brackets.
If the camera and the optics are ordered as a kit,
the components are pre-assembled and shipped
as one unit. Keep the protective cap on the lens
until the mechanical installation is finished.
•
If you must expose the sensor or lens surface,
ensure the environment is as dust-free as possible.
•
Gently blow off loose particles using clean
compressed air.
•
The sensor and lens surfaces can be cleaned with
a soft tissue moistened with water or a water-based
glass cleaner.
•
The length and weight of the optics might be beyond
the capability of the standard mounting bracket
SK5105-L. For this purpose, a second mounting
bracket type SK5105-2L to hold the tube extension
ring(s) is more appropriate.

Control Signals and Timing Diagram
Thus, the frequency of the clock signal determines the
speed at which the charges of the individual pixels of the
line sensor appear in the camera video output. At each
positive edge, the accumulated charges of the subsequent pixels are released as video output.
The control signals needed to run the CCD line scan
camera are "Clock" (CCLK) and "Start Of Scan" (SOS).
The clock signal is generated internally by a programmable oscillator.
The SOS can be initiated internally by adjusting the
Exposure Time or externally by the grabber board. For
internal control, the camera must be set in the 'Free Run'
mode by using command 'M0'. When the SOS signal is
generated by the grabber board then the camera must
be set to the 'external Trigger CC1' mode using 'M3'.
The SK8160CKO-LB camera requires 8482 clock pulses
for a line scan to be read out completely. This corresponds to the number of pixels per line plus several extra
cycles prior and past the charge acquisition.
Accordingly, the line frequency is limited to 1/8482 part
of the clock freqeuncy. Lower line frequency values can
be used without restriction. The minimum SOS pulse
length is 30 ns.
The frequency of the 'SOS' signal determines the number
of lines that are read per second (= line frequency). On
each rising edge of this signal, the accumulated charges
within the sensor are transferred to the analog transport
registers in parallel with the sensor line information.

Advanced Camera Control Functions
Camera Control by Commands
The configuration program SkClConfig provides the option to adjust camera settings, such as gain, offset, trigger
modes, by sending control commands directly.
Similarly, current parameters, as well as specific product information, can be read from the camera using the request
commands. All set and request commands are listed in the tables below.
•
•
The commands are entered in the 'Input' field in the 'Camera Control' section of the "Camera Gain/Offset
Control" dialog. 1
In the 'Output' field, either the acknowledgement of the set commands (0 = OK, 1 = not OK) or the return values
of the request commands are output. 2
The parameter settings are stored in the non-volatile flash memory of the camera and are available after a rapid
start-up, even after a complete shut down or loss of power.

Camera Control and Performing a Scan
„„ Synchronization of the Imaging Procedure and the Object Scan Velocity
•
A two-dimensional image is generated by moving either the object or the camera. The direction of the translation
movement must be orthogonal to the sensor axis of the CCD line scan camera.
•
To obtain a proportional image with the correct aspect ratio, a line-synchronous transport with the laterally
correct pixel assignment is required. The line frequency and the constant object velocity have to be
coordinated.
•
In cases of a variable object velocity or particularly high accuracy requirements then an external synchronization is necessary. The various synchronization modes are described below.
The optimum object scan velocity is calculated from:

Adjustments for Optimum Scan Results
Prior to a scan, the following adjustments and parameter settings should be considered for optimum scan
signals:
•
Lens focussing
•
Integration time
•
Sensor alignment
•
•
Gain/Offset
•
Shading correction
Synchronization of the sensor exposure and
the object surface velocity, trigger mode
options.
A real time line signal facilitates the effective focussing of the line scan camera system, even for two-dimensional
measurement tasks. For determining the correct focus, the edge steepness at dark-bright transitions and the
modulation of the line scan signal are the most important factors.
•
Adjust the focus using a fully opened aperture to restrict the depth of field and to amplify the effects of focus
adjustments.
•
The signal amplitude may require trimming when using a fully opened aperture and this can achieved most readily
by shortening the integration time.
16
Out-of-focus:
Optimum focus:
• Low edge steepness
• Signal peaks are blurred
• High-frequency gray values with low
modulation
• Dark-bright transitions with steep edges
• Large modulation in the signal peaks
• High-frequency gray value variations

„„ Gain/Offset Adjustment
Cameras are shipped prealigned with gain/offset factory settings. Open the "Gain/Offset Control" dialog to re-adjust
or customize these settings.
Gain/Offset Control dialog
The gain/offset dialog contains up to 6 sliders for altering gain and offset. The number of active sliders depends on
the individual number of adjustable gain/offset channels of the camera. When "Coupled Gain Channels" is ticked,
all channels are adjusted synchronously with one slider.
Enter commands for advanced software functions in the 'Camera Control' field (see page 13).

Adjustment principle
1. Offset
2. Gain
To adjust the zero baseline of the video signal, totally
block the incident light and enter "00" (volts) for channel 1.
Illuminate the sensor with a slight overexposure in order
to identify the maximum clipping. Use the Gain slider "1"
to adjust the maximum output voltage.
For a two- or multi-channel sensor, minimize any differences between the channels by adjusting the other
Offset sliders.
A slight signal noise should be visible in the zero baseline.
For a two- or multi-channel sensor, minimize any differences between the channels by adjusting the other Gain
sliders.
For the full 8-bit resolution of the camera, the maximum
output voltage is set to 255 and for 12-bit is set to 4095.

Glossary
Blooming
If by overexposure too many charge carriers are produced
in one or several photosensitive elements (pixels) of the
line sensor, the transport register is „flooded“ with charge
carriers, and also the following register bins are charged
over the saturation limit. This spreading of a local overexposure along a line is called „blooming“. In the resulting
video signal an overexposed area includes too many
pixels. In that area the geometric mapping between
image and object is not correct.
CCD line scan cameras with anti-blooming sensors direct
the abundant charge to a ”drain gate”. Charge overflow
into adjacent, less illuminated pixels is prevented.
Depending on pixel frequency and spectral range,
overexposure up to factor of 50 can thus be handled.
Exposure period
is the illumination cycle of a line scan sensor. It is the 
integration time plus the additional time to complete the
read-out of the accumulated charges and the output
procedure. While the charges from a finished line scan
are being read out, the next line scan is b
­ eing exposed.
The exposure period is a function of the pixel number and
the  pixel frequency. The minimum exposure period of
a particular line scan camera determines the maximum
 line frequency that is declared in the specifications.
The optical resolution of the line sensor is primarily determined by the number of pixels and secondarily by their
size and spacing, the inter-pixel distance. Currently
available line scan cameras have up to 12 000 pixels,
ranging from 4 to 14 µm in size and spacing, for sensors
up to 56 mm in length and line scan frequencies up to
83 kHz.
During a scanning run, the effective resolution perpendicular to the sensor orientation is determined by the
velocity of the scan and by the  line frequency
Pixel frequency
The pixel frequency for an individual sensor is the rate of
charge transfer from pixel to pixel and its ultimate
conversion into a signal.
Region of Interest
A freely programmable window (region of interest, ROI)
can be applied to the line sensor so that only the pixel
information within the ROI can reach the memory.
By only illuminating these ranges, data volume and data
processing is accelerated for both line and a
­ rea scan
acquisitions.
Constraint: the ROI memory allocation must be divisible
by 8.
Integration control
Shading correction
Cameras with integration control are capable of curtailing
the  integration time within an  exposure period.
This performs an action equivalent to a shutter mechanism.
 Shading Correction, section 3.2
SCM
Integration time
Shading Correction Memory,
The light-sensitive elements of the photoelectric sensor
accumulate the charge that is generated by the incident
light. The duration of this charge accumulation is called
the integration time. Longer integration times increase
the intensity of the line scan signal, assuming constant
illumination conditions. The complete read-out of
accumulated charges and output procedure determines
the minimum  exposure period.
 Shading Correction Memories and API Functions,
section 3.2
Line frequency, line scan frequency
SoS (Start of Scan)
is the reciprocal value of the  exposure period. The
maximum line frequency is a key criterion for line scan
sensors as this is the limiting factor for the scan velocity.
is an internally generated trigger signal for sequential
control of the camera, The signal is induced either by an
internal counter or by an external line synchronization
signal, depending on the selected line synchronization
mode.
Two elements of a line scan camera determine the optical
resolution of the system: first, the pixel configuration of
the line sensor and, secondly, the optical resolution of the
lens. The worst value is the determining value. In a phased
set-up, both are within the same range.
24
In addition to  SoS, cameras with  Integration Control
function generate an internal SoI-signal that initiates the
integration period.

 Software: SkLineScan, section 3.1
Synchronization
To obtain a proportional image with the correct aspect
ratio, a line synchronous transport with the laterally
correct pixel assignment is required. The  Line
frequency and constant object velocity have to be
compatible with each other.
For more accurate requirements or with a variable object
velocity, external synchronization is necessary.
 Synchronization of the Imaging Procedure and the
Object Scan Velocity, section 3.2
Thresholding (monochrome cameras only)
The thresholding process generates a binary signal from
the gray scale data, with values below the threshold
yielding 0 and those above yielding 1. Only the pixel
addresses of the location and threshold transition (from
high→low or low→high) are transmitted, reducing data
throughput.
Line Scan Camera SK8160CKO-LB Manual (05.2017) • shared_Glossary.indd (05.2017)
Thresholding is particularly appropriate for measuring
widths or edge positions, by simply masking the r­ equired
pixel addresses.
