Profile measuring device
Micro-Epsilon Messtechnik GmbH&Co KG: The laser-line profile sensor, scanCONTROL 2800, makes use of the triangulation principle for two-dimensional acquisition of profiles on a variety of different 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 CMOS array by a high quality optical system. 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's two-dimensional coordinate system.
A moving object or a scanning sensor will generate a three-dimensional representation of the object.
