RegionSelector

parameter
until the laser line is imaged as a narrow bright stripe and the background is not
visible, see the figure in the middle below.
Figure 34: Too short exposure time: Laser line hardly visible.
Figure 35: Normal exposure time: Laser line bright but not saturated. No background visi‐
ble.
Figure 36: Too long exposure time: Laser line wide and saturated. The background is visi‐
ble.
3.
Set
RegionSelector
to Region1.
4.
Set the
ExposureTime
parameter to the same value as for Region0.
