3D (Peak Detector) settings
This section describes how to the set the 3D properties. These properties are described in
Section 5.2.
1.
Set threshold value for peak 0 with property
Peak0_Threshold
(in category
PeakDetector/Peak
0) (see also note in Section 5.2.3).
2.
Set scan area for peak 0 by setting the start row (
Peak0_3DY
in category
PeakDetector/Peak0
)
the height (
Peak0_3DH
in category
PeakDetector/Peak0
) (see also Section 5.3.2).
3.
Set image (2D) row for peak 0 by setting
Peak0_2DY
(in category
PeakDetector/Peak0
). Note
that this value must be outside the scan areas.
4.
If two peaks are required then repeat steps 1 to 3 with peak 1, replacing Peak0 with Peak1
in the property names.
5.
Set
PeakDetector_Mode
(in category
PeakDetector
) to
Mode_3Donly
or to
Mode_2Dand3D
. Note
that
Mode_3Donly
should be selected for maximal frame rate.
6.
Set
PeakDetector_NrOfPeaks
to the required number of peaks (1 or 2).
7.
If
PeakDetector_Mode
is set to
Mode_2Dand3D
then skip steps 8 to 10 and continue at step 11.
8.
The number of frames of the FrameCombine feature (
FrameCombine_NrOfFrames
) should be
set to a value that the resulting frame rate is below 200 for most applications (see also
Section 5.2.12). The resulting frame rate is the trigger rate divided by
FrameCombine_NrOfFrames
. In free running mode (
TriggerMode
=
Off
) the frame rate can be
read from the property
AcquisitionFrameRateMax
(in category
AcquisitionControl
). The
lower the resulting frame rate, the fewer interrupts are generated by the GigE driver and
the less load is produced on the computer’s CPU. E.g. if the trigger rate is 4000 fps then
FrameCombine_NrOfFrames
should be set to 20 or more.
9.
If FrameCombine is used, then the parameter
FrameCombine_Timeout
(in microseconds)
should be set (see also Section 5.2.12. The value should be higher than the longest time
between triggers, e.g. if the trigger rate is constant, then it could be set to twice the time
between triggers.
10. If FrameCombine is used then
FrameCombine_Enable
should be set to
True
.
11. Read the value of the parameter
HeightInterface
and set
Height
to this value.

Column FPN Correction
Due to the readout structure of the image sensors there is a column-wise fixed pattern noise
(FPN). The Column FPN Correction (ColCorrection) adds or subtracts a fixed value to a column.
These values are obtained by a calibration process. The ColCorrection of the camera was
calibrated at Photonfocus production facility.
7.7.1
Enable / Disable the Column FPN Correction
The Column FPN Correction can be enabled or disabled with the property
ColCorrection_Enable
(in category
Correction
/
ColCorrection
). By default the correction is enabled.
7.7.2
Calibration of the Column FPN Correction
The Column FPN Correction of the camera is correctly calibrated at Photonfocus production
facility. Although a new calibration is normally not required, you can recalibrate the Column
FPN Correction with the following instructions:
