Testing bench for laser triangulation sensors

Laser triangulation is a very efficient non‐contact point‐measurement procedure, very similar to a mechanical gauge, but much faster. However, the special characteristics of the laser triangulation sensor (LTS) must be taken into account for its use. The correct selection of sensor and test‐equipment verification, complying with norm ISO 9001, can be facilitated or implemented with the test‐bench for LTS, developed in the quality and production measurement technology laboratory of the Neu‐Technikum Buchs, Switzerland. A wide range of LTSs has been collated in a market analysis; differences of performance have been determined in a widespread comparison.
