Figure 4-28 Available Filters

The “Filters” button opens a drop-down menu. Two spatial filters are available: “Smoothing” and
“Despeckle”. These tools are great with low quality laser or low level signals. Note that the “Despeckel”
filter is more “aggressive” than the “Smoothing” filter, which makes it ideal for very poor quality beams.

Figure 4-29 Spatial Filter Example

Warning

Smoothing Filter

The “Smoothing” filter performs a 3x3 mask triangular filter. The center pixel has a higher weight (3/11)
than the surrounding pixels (1/11). If the filtered pixel is on the edge, it will set the surrounding pixels
outside the image to 0.

Despeckle Filter

The “Despeckle” filter uses a 9x9 mask flat filter to perform a simple averaging of the central pixel. All
pixels have the same weight (1/81). If the filtered image is on the edge, the surrounding pixels outside the
image will be set to 0.

Beamage Series User Manual Revision 9.0 32

IR Sensors Filter

The “Filters” button also contains the “IR Sensors” correction factor. With a Beamage-3.0-IR camera, this
filter must be activated. Then, a correction factor is applied to the intensity of each pixel, according to the
following correction formula:

4.6.2. Normalize

The “Normalize” button will spread the graph’s (3D, 2D, and XY) intensity over the full range (0% to
100%). Note that only the displays are normalized, the normalization does not affect the centroid and
diameter computations.

4.6.3. Trigger

The “Trigger” button enables the camera to capture images only when an electric signal is sent to the
Beamage via the SMA connector. This can synchronize the system’s capture rate with a pulsed laser
source. A SMA to BNC adaptor is provided (202273). The input trigger signal can be from 1.1 volts to
24 volts. The rise edge response time is 300 ns. The pulse width of the trigger signal must be between
300 ns and 230 ms.

settings and results relative to the beam divergence (refer to section 5.4). To compute the divergence and
abide by the ISO-11146-1:2005 standard, the first step is to place an aberration-free lens between the
Beamage and the laser. The lens should be placed in the far-field of the laser beam while the Beamage
should be at the focal point of the lens. The second step is to enter the focal length of the lens in the
software. Since the focal length is wavelength dependent, make sure to use the correct value for your
laser in the settings. The divergence in both main axes (x and y) are computed as defined by the ISO­11146-1:2005 and ISO-11146-2:2005 standards and displayed at the bottom of the “Divergence” tab.

Beamage-M2 accessory. For more information on how to use this mode, please refer to the Beamage-M2
manual which can be found in the Help section (refer to 4.8.3).

The M2 factor can be considered as a quantitative indicator of laser beam quality. In terms of propagation,
it is an indicator of closeness to an ideal Gaussian beam at the same wavelength. Paired with a
Beamage-3.0 beam profiling camera, the Beamage-M2 module can provide Real-Time M2 measurements
directly in the PC-Beamage software. The calculations are based on the second order spatial moments
and therefore are fully compliant to the ISO 11146 and 13694 standards.

Unlike other M2 measurement systems, the Beamage-M2 can measure the propagation parameters of a
laser beam without the need of any moving part or an external power supply, providing calculation of the
M2 factor in less than a second. This condition allows the possibility to do on-line monitoring. Its modular
design allows users who only want to measure the energy or intensity spatial profile of their beam to
remove the Beamage-3.0 from the M2 module and use it as a simple beam profiler.

The crosshair definition will affect the XY Display (refer to section 6.36.3)

and the beam width if it is defined by the FWHM or 1/e2 along crosshair

5.1.1. Main Controls

The “Main Controls” section allows the user to set the desired beam diameter definition and crosshair
position. Use the drop-down menu to select the desired settings.

5.1.1.1. Beam Diameter Definition

By default, the beam width definition is set to “4 sigma (ISO)” which respects the ISO-11146-1:2005 and
ISO11146-2:2005 standards (refer to Appendix A. ISO11146 and ISO11670 Definitions). This definition
takes the entire image to compute the beam parameters, which slows the computation time and reduces
the frame rate.

The “FWHM along crosshairs (50%)” finds the crosshair’s Full Width Half Maximum (FWHM). The

algorithm will return the width corresponding to the curve’s first half maximum and the curve’s last half

maximum. Because the beam definition only takes into account a slice of the beam, the computation time
is much faster and higher frame rates can be achieved.

The “1/e2 along crosshairs (13.5%)” finds the crosshair’s width corresponding to 1/e2 (about 13.5%) of its
maximum. Similarly to the FWHM, this beam definition will increase the frame rate.

The “86% effective diameter (D86)” computes the circular beam containing 86% of the total intensity. This
definition assumes the beam is circular.

5.1.1.2. Crosshair Definition

The crosshair is defined by its center (intersection of the 2 crosshairs) and its orientation. The crosshair
center can be set to the beam’s centroid as defined by the ISO-11146-1:2005 and ISO-11146-2:2005
standards, the beam’s peak position or at a user-defined fixed position. If many pixels correspond to the

peak value, the crosshair’s center will be set to the first peak.
The crosshair’s orientation is set to “Auto Orient” by default, which aligns it to the beam’s orientation as

defined by the ISO-11146-1:2005 and ISO-11146-2:2005 standards. It can also be set to a fixed 45° or 0°
angle, or at a user-defined fixed angle.

Warning

5.1.2. Measures

The “Measures” section presents the beam’s diameter and centroid information according to the selected
beam definition (refer to section 5.1.1.1).

The computation algorithm first determines an approximate beam diameter (13.5% clip level). The
algorithm will consider that all pixels outside 2 times the approximate beam diameter are the outside area.
The outside area’s average will become the baseline, which will be subtracted from the area containing
the beam. Only the area containing the beam will be used to compute the diameter. This means that a
smaller beam will have a smaller area which will decrease the computation time and increase the frame

example, for “86% effective diameter (D86)”, only the effective diameter

rate. If the beam is larger and all pixels contain the area containing the beam, there will be no baseline
subtraction and the frame rate will be slower.

5.1.2.1. Diameter

The “Major Axis” is the beam maximum width whereas the “Minor Axis” is the minimum beam width.
The “Effective Diameter” is the beam’s diameter considering it is circular.

The effective diameter is only valid if the ellipticity is greater than 87%. If the beam’s ellipticity is lower

than 95%, the effective diameter will by grayed-out, indicating it is not valid.
The “Ellipticity” is the ratio between the minor axis and the major axis. For a perfect round Gaussian

beam, the ellipticity would be equal to 100%.
The “Orientation” is defined as the “angle between the x-axis […] and that of the principal axis of the

power density distribution which is closer to the x-axis.”

. From this definition, the angle is comprised

between -45° and 45°.
For more information on beam diameter computations as defined by the ISO-11146-1:2005 and ISO-

11146-2:2005 standards, please refer to Appendix A. ISO11146 and ISO11670 Definitions)

Test methods for laser beam widths, divergence angles and beam propagation ratios, 2005, Geneva

Beamage Series User Manual Revision 9.0 43

Figure 5-3 Fixed Coordinates System for the Sensor

The beam “Centroid” corresponds to the beam’s first order distribution as defined by the ISO-11146­1:2005 and ISO-11146-2:2005 standards (refer to Appendix A)

The beam’s “Peak” position corresponds to the pixel’s peak value position. If many pixels correspond to
the peak value, the crosshair will be centered on the first peak.

The beam “Peak to Average Ratio” corresponds to the ratio between the actual beam peak value and the
height of an equivalent simulated flat-top beam. The simulated beam’s width is the 1/e2 diameter of the
actual beam and has the same area (same energy). The software computes the ratios for both the X and
Y axes.

These results are only available when the “1/e2 along crosshairs (13.5%)” beam diameter definition is
selected. If any other definition is used, the “Peak to Average Ratios” are not computed and dashes are

displayed. When the crosshair center is set to “Centroid” instead of “Peak”, results are grayed out to
remind the user that the values do not correspond to the “Peak to Average Ratios”.

Exposure time: Controls the Beamage sensor’s exposure time.

Image orientation: Rotates or flips the captured image.

Image Averaging: Applies a temporal filter by averaging multiple frames

Active Area: Selects the region of interest.

Pixel Addressing: Reduces the spatial resolution by averaging or decimating pixels.

5.2. SETUP

The “Setup” tab allows the user to set the Beamage parameters.

Figure 5-6 Setup Tab

Beamage Series User Manual Revision 9.0 46

Gain: Adds numerical gain to captured image.

ADC Level: Selects the BEAMAGE’s ADC level for each pixel

Pixel Multiplication Factor: Adjusts the pixel multiplication factor when using optical components

If the beam is still saturated at a 0.06 ms exposure time, please increase

the attenuation in front of the Beamage. If the beam intensity is too low at

200 ms exposure time, please lower the attenuation in front of the

Beamage.

When the Beamage is not capturing images and is in “Animate” mode or

buffer viewing mode, it will neither flip nor rotate the current image, as it

has already been captured.

5.2.1. Exposure Time

The “Exposure Time” controls the Beamage’s exposure time settings. It can be set from 0.06 ms to
200 ms. The “Auto” option will automatically set the exposure time in order to have the maximum beam
intensity at 85% of the sensor’s saturation level. The exposure time can also be set manually by clicking
on the corresponding radio button and changing the value in ms.

Tip

5.2.2. Image Orientation

The “Image Orientation” controls rotate or flip the captured frame. The captured frame can be rotated to
90⁰, 180⁰, or 270⁰. All angles rotate clockwise. The captured frame can also be flipped horizontally or
vertically. If a frame is saved with a rotation and/or a flip, it will keep these orientation settings. Note that
the reference axis for the centroid is neither flipped nor rotated. All positions are always relative to the
image’s center which is (0,0) and the horizontal axis always increases towards the right-hand side and
the vertical axis always increases towards the top.

Warning

Beamage Series User Manual Revision 9.0 47

Image Averaging will smooth the beam fluctuations that can occur over

time. It is very useful when working with unstable laser sources.

When working with small beams, optimize the speed of the data

transfer and still maintain accurate results, by using an Active Area that is

twice the size of your beam.

Initial image (no rotation, no flip) Flip horizontal 90° rotation Flip & rotation

Figure 5-7 Image Orientation Examples

5.2.3. Image Averaging

The “Image Averaging” function is a temporal filter that captures a specified number of frames (2, 5, or

10) and averages the frames pixel by pixel to create a single time-averaged image. This lowers the total
frame rate because multiple frames need to be captured for one computation.

Tip

5.2.4. Active Area

The “Active Area” function allows the user to select a region of interest (ROI) on the sensor. This will
increase the frame rate, as fewer pixels need to be transferred from the Beamage. This can only be done
on small beam sizes, since a cropped beam would invalidate the beam width measurements.
Furthermore, to have an accurate measurement, the active area must be at least 2 times the beam size.

The user can select the desired area from a preset selection or enter a custom size. By default, the area

will be placed at the sensor’s upper left corner pixel (0, 0). This position can be changed by entering the

active area’s upper left position. Checking the “Center” check box will center the active area to the
sensor’s center.

Full Resolution

Average 2x2

Decimate 2x2

When working with large beams, optimize the speed of the data transfer

by reducing the spatial resolution using the Pixel Addressing function.

If the Beamage is set in 12 bit mode, it will slow the frame rate.

5.2.5. Pixel Addressing

The “Pixel Addressing” mode allows the user to downsample the captured image. The “Average 2x2” will
take a 2x2 pixel cluster and return its average as one larger pixel. The “Average 2x2” function is only
available in the 12 bit ADC mode. The “Decimate 2x2” will only return 1 out of the 4 pixels. Because the
pixel area is doubled with this mode, it can be used with large beams, where the spatial resolution is not
crucial. It will increase the frame rate because fewer pixels are transferred from the Beamage.

Figure 5-8 Pixel Addressing Mode

Tip

5.2.6. Gain

The “Gain” setting allows the user to set a numerical gain on the captured image. The gain must be
between 1 and 10. If the pixel value is over the maximum ADC level (For 12-bit  212 = 4096), the pixel
value will be topped at the maximum ADC level.

5.2.7. ADC Level

The ADC level is the pixel’s depth which can be set to 12 or 10 bit. In the 12 bit mode, each pixel value is
on 212 = 4096 levels while the 10 bit mode is on 210 = 1024 levels. The 12 bit mode has a slower frame
rate.

Warning

5.2.8. Pixel Multiplication Factor (PMF)

If the Beamage camera is operated with an optical component that has magnification properties (such as
a magnifying lens, a UV Converter or an IR Adaptor), the Pixel Multiplication Factor must be adjusted in
order to have the exact beam dimensions. The “Pixel Multiplication Factor” section can be found at the
bottom of the “Setup” tab.

Beamage Series User Manual Revision 9.0 49

The default value for the Pixel Multiplication Factor is 1.

Tip

Figure 5-9 Pixel Multiplication Factor

It is possible to manually set a value for the PMF. Simply enter the desired value in the white box and
press enter. The beam dimensions will be adjusted accordingly. If a camera lens is used with the
Beamage camera, it is possible to follow the camera lens calibration steps by clicking on the “Calibrate”
button. This will open the “Camera Lens” tab. Refer to section 5.6 for more information about the camera
lens calibration

5.3. DATA ACQUISITION

The “Data Acquisition” tab allows the user to set the acquisition parameters. It is possible to save the
beam profiling results shown in the “Measures” tab (refer to section 5.1.2) in a *TXT file. The *TXT file
includes a header, containing the acquisition settings, followed by the data. Each line corresponds to a
single frame and all the measurements are separated by a tab. This file can be opened in a spreadsheet
software, such as Microsoft Excel. It is also possible to save the images associated with the
measurements saved in the *.TXT logging file. Each image will be individually saved in a native *.BMG
file.

Figure 5-10 Example File of a Measurement Acquisition

To start the acquisition, click on the “Start Data Acquisition” button in the “Main Controls” (refer to section

4.3.4).

Beamage Series User Manual Revision 9.0 50

Each *.BMG file can take up to 8.50 MB on the hard drive. Acquiring
multiple frames can quickly sum up to multiple GigaBytes. If the total

acquisition if over 1 GB, a warning message will appear. If there is only 10

GB left on the hard drive, a warning message will appear and the

acquisition will be stopped.

Fast acquisition should be done on the computer’s hard drive and cannot
be done on an external drive or on a server hard drive since it could slow

down the acquisition.

Figure 5-11 Data Acquisition Tab

The “Duration” defines the time for which the acquisition will keep running. The countdown starts as soon
as the user presses the “Start Data Acquisition” button located in the “Main Controls”. The user can select
the number of days, hours, minutes and seconds.

The “File Name” allows the user to specify a name and a path for his file. A filename must be defined to
start an acquisition. If the “Full images and measurements” is selected, then a series of “.BMG” files with
the same filename concatenated with its corresponding increment will be saved.

The “Sample Rate” defines the rate at which the samples are saved. When choosing the “Measurements
only” acquisition mode, the sample rate is defined as 1/X images. To save every frame computed, enter
the value “1” in the box. To keep track of only a small amount of frames, enter a higher value. When
choosing the ‘Full images and measurements” acquisition mode, the sample rate is defined temporally.
The fastest rate is limited to 1 per second.

Warning

Beamage Series User Manual Revision 9.0 51

The Beamage sensor must be placed precisely at the focal point, not at

the beam waist.

5.4. DIVERGENCE

The divergence tab opens when the divergence button is clicked in the Main Controls (refer to section

4.6.5).
To compute the divergence and abide by the ISO-11146-1:2005 standard, the first step is to place an

aberration-free lens between the Beamage and the laser. The lens should be placed in the far-field of the
laser beam while the Beamage is at the lens’ focal point. The second step is to enter the lens’ focal length
in the software. Since the focal length is wavelength dependent, make sure to use the correct value for
your laser in the prior settings. The divergence in both main axes (x and y) are computed as defined by
the ISO-11146-1:2005 and ISO-11146-2:2005 standards and displayed at the bottom of the “Divergence”
tab (refer to Appendix A).

Beamage Series User Manual Revision 9.0 72

7.1.7. The Example VI.

The VIs have all been used to create an example software. The front panel of this example is shown
below.

The example is written to be easy to use and understand so as to aid in the development of custom
LabVIEW software. It uses an event structure to show the various controls. To use the example:

1. Copy the VIs into the folder of your choice, along with the supplied DLL file.

2. Start LabVIEW and run the example VI.

3. The VI will check to ensure the DLL is present. A warning will be issued if it cannot be located,
and the required location will be displayed. Place the DLL in that location.

4. Plug a Beamage Camera into a USB port on the PC in use. Start PC-Beamage and let it connect
to the camera.

Beamage Series User Manual Revision 9.0 73

5. Under the Show/Hide Options menu item, select Start LabVIEW Pipeline. The PC-Beamage
software will verify the connection. You may now minimize the PC-Beamage software as LabVIEW
can now control the functions.

6. Press the Connect PC Beamage button on the LabVIEW software. The Connected LED will turn
on. The VI will ask the PC-Beamage for some information, and the software Version and Serial
Number indicators will appear.

7. Press the Start Capture button. The Selected measurements will activate. Use the Main, Display,
Activate buttons, and Measurements controls to select the desired measurements. The Activate
buttons are only visible when the XY Display is selected.

8. Pressing Disconnect or Exit will automatically stop all measurements and close the LabVIEW
pipeline.

8. TROUBLESHOOTING AND TIPS

8.1. WHILE TRYING TO INSTALL PC-BEAMAGE, THE FOLLOWING MESSAGE APPEARS: THE
PROGRAM CAN’T START BECAUSE MSVCR100.DLL IS MISSING […]

You must download the missing dll from Microsoft software and install it on your computer:

32 bit: http://www.microsoft.com/download/en/details.aspx?id=5555
64 bit: http://www.microsoft.com/download/en/details.aspx?id=14632

8.2. BEAMAGE IS NOT DETECTED

Make sure the Beamage is connected to a USB 3.0 Super Speed port. The Beamage will work if plugged
directly in a USB 2.0 port at a slower transfer rate.

Close the software application, disconnect and reconnect the USB 3.0 to the Beamage and open the
software application. The LED indicator on the Beamage should blink in green and then in red before
turning on green. If the LED does not turn on at the software’s startup or if it does not turn on completely,
please contact your Gentec-EO representative or contact us at [email protected].

8.3. THE DISPLAY AREA IS COMPLETELY WHITE

Press the “Refresh” button and the display should come back.

8.4. CHANGING THE OPTICS IN FRONT OF THE BEAMAGE

Because the Beamage’s sensor does not have a coverglass, it is very sensitive to dust. Change the
optics in a clean environment and put the Beamage’s aperture facing down to minimize the dust.

8.5. SMALL BLACK SPOTS APPEAR ON THE IMAGE

If these small black spots do not change place even if you rotate the attenuation filter, it is probably dust
on the sensor. DO NOT TOUCH the surface of the chip to remove the dust as this will damage the
sensor. AT YOUR OWN RISK, you can use an oil-free air jet to blow the dust away or contact your
Gentec-EO representative.

8.6. IT IS NOT POSSIBLE TO START AN ACQUISITION. IT KEEPS OPENING A WARNING
MESSAGE INDICATING THAT 0 GB IS AVAILABLE ON HARD DRIVE

This is probably due to the fact the path in/ which the PC-Beamage was not installed in the default
C:\Program Files\GENTEC-EO\PC-Beamage directory.

8.7. THERE IS NO SERIAL NUMBER DISPLAYED IN THE CAMERA

 Please close the PC-Beamage software program, wait a couple of seconds and open the PC-

Beamage again.

 If the problem persists, please verify in Window’s Task Manager if there is only one PC-

Beamage.exe instance running. If more than one are running, end all processes and open PC­Beamage again.

 If the problem persists, please disconnect the Beamage and connect it again.

Beamage Series User Manual Revision 9.0 75

 If the problem persists, please contact your Gentec-EO representative or contact us at

[email protected].

8.8. THE DETECTED SERIAL NUMBER IS 000000

This happens when you connect a Beamage for the first time in a new USB port. The drivers need to be
installed each time a new Beamage is plugged for the first time in a new USB port. When this happens,
the PC-Beamage software often opens before the drivers are installed, indicating a 000000 serial
number. Close the PC-Beamage software and restart the application.

8.9. THE 10 BIT ADC LEVEL IS NOT AVAILABLE EVEN WHEN THE BEAMAGE IS
CONNECTED TO A USB 3.0 PORT

The 10 bit ADC level is only available when using a USB 3.0 port. If it is not available even when
connected on a USB 3.0 port, reboot the computer. If it is still not available, please contact your Gentec­EO representative or contact us at [email protected].

8.10. DO NOT DISCONNECT THE BEAMAGE WHILE IT IS STREAMING

The Beamage must not be disconnected when it is streaming.

8.11. TIPS TO INCREASE THE FRAME RATE

The Beamage’s frame rate greatly depends on the computer’s performances. Here are a few tips to
increase the frame rate:

 Use a USB-3.0 port;
 Use a computer with high performances (refer to PC Requirements section 1.2);
 Use Windows 7 or Windows 8;
 Follow the PC operating state for optimal conditions (refer to section 1.2)
 Do not use Filters (refer to 4.6.1);
 Do not use Image Averaging (refer to 5.2.3);
 For a large beam, use Pixel Addressing (refer to 5.2.5);
 For a small beam, use an Active Area (refer to 5.2.4);
 Make sure you have a short exposure time;
 Do not stream multiple Beamage units simultaneously.

APPENDIX A. ISO11146 AND ISO11670 DEFINITIONS

The beam centroid coordinates are given by:

The beam widths are defined as an “extent of a power density distribution in a cross section of beam

based on the centered second order moments of the power density distribution.”

The second order moments of power density distribution are given by:

The beam widths are given by:

where:

The major axis is the width’s maximum whereas the minor axis is the width’s minimum.
The effective diameter of the beam is an “extent of a circular power density having an ellipticity greater

than 0.87. […] If the ellipticity is larger than 0.87, the beam profile may be considered to be of circular

symmetry at that measuring location and the beam diameter can be obtained from:”

The beam ellipticity is the “ratio between the minimum and maximum widths”
The beam orientation is the “angle between the x-axis […] and that or the principal axis of the power

density distribution which is closer to the x-axis.” From this definition, the angle is comprised between 45°
and -45°.

Beamage Series User Manual Revision 9.0 78

The beam’s divergences transformed by an aberration-free focusing element of focal length f are given
by the following equations:

In the laboratory or usual system of coordinates (X’,Y’,Z’), the coordinates of the latest calculated position
of the centroid for both X’ and Y’ axes are given by the following equations:

The coordinates of the mean position of all computed centroids for both X’ and Y’ axes are thus defined
by the following equations, which are simple arithmetic means,

Where and are the centroid coordinates for X’ and Y’ axes already saved in the buffer, and n
the number of computed centroid positions saved in the buffer.

The azimuth angle, which is the angle between the usual X’ axis and all computed centroids, is given by
the following equation:

where we have the following definitions:

In the beam axis coordinate system (X,Y,Z), the beam positional stability values in the azimuth direction
(X) and perpendicularly to the azimuth direction (Y), which are 4 times the standard deviations of all
computed centroid values, are given by the following equations:

The overall positional stability is given by:

Beamage Series User Manual Revision 9.0 79

In the previous 3 equations, the standard deviations are defined by the following equations:

and are derived from and by transformation of coordinates. (X’,Y’,Z’) is the usual or

laboratory coordinate system and (X,Y,Z) is the beam axis coordinate system.
The RMS standard deviation value of the centroid position, which is not an ISO standard, is given by the

following equation:

where are relative values.
