Functionality

The sensor is used to measure the surface profile of an object along a laser line projected onto
the object. The measured surface profile can be retrieved by the user – either via the integrated
web server, the UDP interface or the SDK (software development kit). Sensors in the OXM ver-
sion have additional integrated functions (tools) that allow carrying out geometric measurements
on the profile (such as width, height, circle diameter or angle). These measurement results are
then available via the integrated process interface, switching outputs or the analogue output.
Triangulation principle
The sensor works according to the laser triangulation principle:
1. Via a cylindrical lens, a laser beam is expanded to a laser line and projected onto the sur-
face of the measurement object.
2. The measurement object reflects the laser line.
3. The reflected laser line is projected onto a surface camera in the sensor.
4. The sensor uses the camera image and stored calibration data to calculate the profile of a
measurement object.
