Advanced Laser Triangulation Functions

• AutoStart

The 3D image acquisition begins as soon as the laser line reaches a predefined position in the AOI. Acquired 3D data before start trigger are also available (History Mode).

• Suppression of Disturbing Reflexions

• Automatic AOI Search

Automatic detection of laser line position in the sensor image. Useful when scanning objects with different height.

Integrated Filtering of Line Position Data:

min < Gauss Width < max

min < Sum of Intensity < maxReflexion


The position of AOI (AoiOffsetY) is automatically updated to track the line position in the sensor image. Advantage: High Profile Speed by Scanning a big Z-Range

AoiOffsetY=600 AoiOffsetY=400 AoiOffsetY=200
