53Operating the Beam Profiler
Region of Interest (ROI)
The ROI defines a subarea within the maximum available camera sensor surface,
whereas the maximum ROI is 1360 x 1024 (full size) and the smallest 32 x 32 pixel.
Only image data of the selected ROI are transmitted from the Camera Beam Profiler
to the PC so that a narrowed ROI size reduces bandwidth requirements and
therefore increases measurement speed (frames per second, fps)
There are some predefined ROIs which can be selected by clicking to the
appropriate control entry.
By selecting a predefined ROI it is automatically centered to the sensor center. See
the preview image for visualizing the adjusted size which is displayed as a yellow
rectangle. To shift the selected ROI within the available sensor area click right into
this rectangle and drag the mouse.
You may also chose a user defined ROI. Just draw a rectangle into the preview
