Patented Technology
System Presentations (cont.)
The Beam Analyzer provides a bridging technology, producing the 3D intensity
reconstruction of CCD cameras, while being capable of measuring very
small spots at high resolution and huge dynamic range
2D and 3D Intensity Plots
The measuring technique is based on a multiple scanning knife-edge technology, combined with a tomographic image
reconstruction for the creation of the 2D/3D display. When the drum spins, the knife-edges cut across the beam in an
orthogonal plane to the direction of propagation. A stationary large detector inside the spinning drum measures light
intensity. For attenuation, when needed, a built-in distortion free optical filter is inserted between the spinning drum
and the detector. This technique provides the required attenuation without affecting beam quality. Each scanning
knife-edge is oriented at a different angle on the drum and moves across the beam path in a different direction as the
drum rotates. Consequently, during a single rotation of the drum, the instrument generates a set of profile curves,
each representing the intensity profile of the beam from a different direction. This data is the input for the tomographic
reconstruction algorithm to generate the 2D/3D intensity profile
of the beam.
The Beam Analyzer is offered in two types of measuring heads:
The BA7 uses seven individual knife-edges, providing more accurate
Filter
Knife edge
measurement of the true beam shape and dimensions by gathering
data from all 7 scans, while the BA3 uses only three knife-edges,
and is recommended for smaller beams measurement as well as for
Sensor
Laser Beam
a near-Gaussian beams. The more knife-edges, the greater the level
of detail obtained. For a beam distribution that is significantly nonGaussian the BA7 would reconstruct a plot that closely matches the
Rotating drum
real beam.
The Projection function provides either a 2D or a 3D plot of the beam intensity profile,
and is created using reconstructive tomography.
The 2D contour maps and the 3D isometric plots can be displayed with or without scan axis and grids. These plots
can be rotated along the beam optical axis, as well as be flipped. This feature enables the user to view the image from
various angles around the beam. It is also possible to control the 3D plot wire density.
Data about the beam size and centroid position is displayed digitally along with centroid and beam size data.
2D Plot
3D Plot
Power Measurement
The beam power can be displayed either as a digital readout, or as a bar-type
display or in combination with an analog “needle”. Power presentation units can
be chosen as mW, µW or dBm. The user can offset the zero to deactivate the
ambient light suppression. Pre-defined filter transmission files can be selected.
A test range can be defined and displayed to monitor beam power within specific
limits, audio alarms are optional.
System Presentations
Beam Analyzer provides an extensive range of graphical presentations and analysis of laser beam parameters.
Beam Position and Ellipticity
Beam Profiles and Width
The beam centroid position is continuously monitored relative to
the center of the sensor area in real-time, along with beam shape,
ellipticity (major and minor axes) and angular orientation. A zoom
function is available for viewing the footprint of small beams
more clearly.
Observing beam position stability versus time is available upon
setting up of the Chart function to monitor beam position at the
selected clip level.
Beam Analyzer’ control software simultaneously displays two profiles from
two orthogonal knife-edges, or show each profile individually for greater visual
detail. These main profiles, located at 45 degrees from the base of the head,
are called “V” and “W”.
Beam widths are digitally displayed for any three user selected clip levels,
with up to 0.1µm resolution. The beam profile displays are auto-scaled (optional)
to maximize on-screen detail and resolution. Added detail can be obtained in
a special high-resolution mode. A Gaussian fit profile can be overlaid on
profiles in real time, while the correlation and fit values are displayed digitally.
Zoom function automatically increases the displayed spatial resolution.
Chart mode
It is frequently necessary to monitor the Beam Width (or
alternatively Beam Position) as a function of time. In Chart
Mode, these parameters can be viewed in strip chart format,
showing long term time-dependent stability or drift. The
measured data can be viewed on screen, saved or printed for
further analysis.

System Presentations
BeamOn provides an extensive range of graphical presentations and analysis of laser beam parameters.
Beam Profiles and Width
Two types of profiles are being displayed;
Sum Profiles-Displays the two orthogonal
profiles, one along the vertical axis and one
along the horizontal axis. Each profile is
composed of a summation of rows
Horizontal Profile
and columns at a beam cross-section.
Line Profiles-Displays the beam contour along a line parallel to
the vertical and horizontal axes. These two orthogonal lines are
designated as a cross hair cursor on the image plane and can be
moved along the working area.
Results
Beam widths are digitally displayed for any three user selected clip levels.
A Gaussian fit profile can be overlaid on profiles in real time, while the correlation and fit values
are displayed digitally. A Top Hat profile presentation and fit is also available.
2D and 3D Intensity Plots
The Projection function provides either a 2D or a
3D plot of the beam intensity profile. A zooming
feature enables magnification of the displayed
image. It is possible to control the 3D plot wire
density. For a weak beam image, even at max
shutter and gain settings. Use the beam intensity
pallet to optimize color display.
Beam Intensity Pallet
The 3D plot can be rotated along
the beam optical axis, as well as
be flipped. This feature enables the
user to view the image from various
angles around the beam.
3D Plot - side view
3D Plot - top view
2D Plot
Power Measurement
The beam power is displayed as a digital readout at the status bar. A power calibration function
allows the user enter a “base” power value. In subsequent captured images the summed intensity
of all pixels will be proportional to this value.

System Analysis
BeamOn provides an extensive range of laser beam parameters calculation and analysis.
Beam Position
The beam centroid is continuously monitored relative to the center of CCD head. Three Regions
of Interest (ROI) can be defined by the user, thus enabling the user to monitor up to 3 beams’
centroids simultaneously.
Detailed Statistics
The information in Statistics screen is updated in real time and
is useful for analyzing beam characteristics. It lists the information
in a table format and shows the actual measurement values, as
well as the MIN (minimal measurement), MAX (the maximal
measurement), AVER (the averaged value), and STD (the
standard deviation) of several parameters which are crucial for
beam analysis:
- Centroid (H / V profiles)
- Beam Peak (H / V Proflies)
- Beam width at 3 clip levels (H / V Profiles)
- Correlation to Gausian profile (H / V Profiles)
- Power (mW)
Statistics
Analysis and QA Testing
Elipse estimation
Distance measurement
Test
The software enables a best fit to an elipse as
well as direct distance measurement.
The Elipse function calculates the best-fit
elipsoid for the examined beam. The major and
minor axes of the fit elipse are calculated as well
as the orientation of the major axes of the fit.
The Distance measurement function calculates
the distance between any two points on the beam
image, the points are being selected by the user.
The Test routine allows the user to test a laser
beam based on user-defined Pass/Fail criteria.
The test results are calculated for any one of the
beam calculated parameters.
