Terms relating to coordinate metrology with optics, probe, computed tomography and multi-sensor systems

Laser distance sensor

Laser sensor

The triangulation sensors often used in automation technology are only suitable for less precise measuring tasks: The laser beam and the axis of the sensor's imaging optics enclose an angle of a few 10 degrees. Thus, a triangle is formed between the laser source, the measurement point and the sensor, from which the distance sought is determined via angular relationships. Foucault laser sensors such as the Werth Laser Probe use the aperture angle of the sensor's imaging optics as the triangulation angle. With suitable software, the measurement uncertainty is reduced to such an extent that it meets the requirements of highly accurate coordinate measuring machines.
