5.2.4.2 Spot Field Panel
The Spot Field panel shows the direct view of the image taken by the CMOS camera. Intensity
levels are displayed as gray scale levels from 0 (black) to 254 digits (white), while saturated
pixels are displayed in red.
The camera resolution and the number of spots in the horizontal and vertical direction can be
selected in the
Camera Settings panel. The Camera Image Size should be chosen slightly
larger than is required to display the entire beam. This ensures that the entire beam is analyzed
as well as minimizing the unused area of the camera sensor. Pixels that are not illuminated by
the beam can contribute to measurement error, and including them in the data analysis also de-
creases the measurement speed. Note that the camera image size affects the camera resolu-
tion, which is the pixel dimensions of the active sensor area.
Additional graphical elements described in the following can be displayed as overlays on the
image.
