Abstract

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.
