2.6.1 Problems with data quality
Error Possible cause Solution
Local noisy data in the point
cloud.
Dust or dirt on the workpiece amplifies
the laser signal.
Clean the workpiece.
Local modification of the surface
properties of the workpiece.
-
Noisy zone in the point cloud in
a certain part of the laser beam.
Highly reflective surface of the
workpiece causes direct reflection back
to the sensor.
Change workpiece alignment.
Finger prints or dirt on the sensor
windows.
Clean the optical windows
(see chapter 2.7.1).
The sensitivity has decreased or
the recommended gain factor
settings (see chapter 1.8.2) do
not allow the laser scanner to

Finger prints or dirt on the optical
windows of the laser scanner.
Clean the optical windows
(see chapter 2.7.1).

2.6.2 Error during operation
Error Possible cause Solution
Laser beam is emitted, but data
cannot be recorded.
The workpiece is outside the measuring
range.
Adjust the measuring distance
and depth and check with a
bright workpiece.
The surface cannot be measured.
Increase the sensitivity of the
laser scanner by setting the gain
factor correctly (see chapter
1.8.2).
The laser scanner is faulty.
Contact the service department
