Laser Line Profile Sensor
The scanCONTROL laser-line profile sensor makes use of the triangulation principle for the two-dimensional acquisition of profiles on the most varied of target surfaces. In contrast to familiar point laser sensors, a line optical system projects a laser line onto the surface of the object to be measured. The back-scattered light from the laser line is registered on a sensor matrix. Along with distance information (z-axis), the controller also calculates the true position along the laser line (x-axis) from the camera image and outputs both values in the sensor two-dimensional coordinate system. A moving object or sensor will generate a three-dimensional representation of the object.
