Abstract

In this paper a laser diode multisensor system for 3D free form surface non-contact measurement is described. The basic measuring principle is the optical triangulation method. The influence caused by the measured surface inclination is discussed first. Two prototypes of this system have been developed. One is the laser star multisensor system and the other is the linear polarized laser sensor with four PSDs. There are suitable to measure the machined 3D free form surface as well as the 3D free form surface made of `soft' materials such as clay and wood. The detected displacement is +/- 2 mm and the surface inclination could be up to +/- 90 degrees without a rotation servomechanism to track the surface normal. The computer simulation and experimental results are given.
