Automatic Exposure Time Regulation
The automatic exposure time regulation facilitates the recording of the profile with optimum exposure time
(shutter time).
The
Shutter time
preset by the user is used as the starting value for the automatic exposure time regula-
tion. It should be selected so large that still valid measured values can be output at the darkest place of the
pro-file. One of the supplied demonstration programs can be used for determining this. The automatic expo-
sure time regulation can also be deactivated if required.
If there is no object in the measuring range, the “shutter time” stored in the shutter register of the sensor will
be used as exposure time. This value must also guarantee reliable recognition of the darkest measurement
object.
A previous test is recommended if the target is very dark or has very high contrast. The various demonstra-
tion programs are suitable for adjusting and testing the exposure time. In doing so, it is by all means sensible
to work with several different exposure times and to observe the effect in the diagrams.
The current exposure time can be calculated from the timestamps of the measured values. It is displayed as
Shutter time, see
