Functionality of Profile / Light section sensors
The sensor measures the surface profile of an object along the reflected laser line. The measured surface profile can be retrieved by the user via the integrated web server, UDP interface or SDK (software development kit). The sensors in the OXM version have additional integrated functions that allow geometric measurements on the profile, such as width, height, circle diameter or angle. These measured values can be used via the integrated process interface, switching outputs or analog output.
Triangulation Principle
The sensor works on the principle of laser triangulation:
- Using a cylindrical lens, the laser beam is expanded into a laser line and reflected onto the surface of the measured object.
- The measured object reflects the laser line.
- The reflected laser line is reflected onto the surface camera on the sensor.
- The sensor calculates the profile of a measurement object using the camera image and stored calibration data.
