interrupted laser line
If the sensor is inclined forwards or backwards, make sure that the laser line reflected by the object
can be detected by the receiver.
It can be ensured that the receiver detects the laser line by reducing the inclination angle or rotating
the sensor by 180°.
The use of the “Vision Assistant” software facilitates the detection of such problems.
5.2.3 Saturation and signal loss
The sensor automatically sets the exposure time for the capture of the height profile so that saturation
is avoided.
Highly reflective surfaces lead to extreme contrasts. In some cases, this may lead to individual points
within the ROI not being detected.
Avoid signal losses by slightly changing the sensor position:
•
incline the sensor laterally or frontally
•
increase or decrease the object distance
