The two line detection could also be used to eliminate vibrations and elastic deformations of
the inspected work piece. This is often used in fast profile scanners where the profile guidance
is on the limits. Vibrations and elastic deformations could be detected by interpreting the local
height gradients of the two laser lines during inspection. A change in the 3D profile, for
instance a shape defect, always gives a change in the local gradient, whereas a vibration or
elastic deformations does not. This fact can be used in software algorithms to compensate
vibration effects and increase the accuracy of the measurements.

Laser Line Detection
The laser line detector takes a threshold value as its input. The threshold has two purposes:
