Abstract:
1. An optical measuring device using optical triangulation for measuring, relative to a plane reference surface (L) and in a direction substantially perpendicular to said reference surface, the distance (d) and the inclination in two directions of a surface (W) to be checked, which locally can be likened to a plane, and comprising: light emitter means ( beam divider means ( an optical splitter ( an optical beam combiner ( sensor means ( which are fewer than or the same in number as that of the multiple light beams, which are placed in a configuration that is correlated with that of the multiple light beams in such a way that each optronic sensor ( which are suitable for delivering (at 20) an output signal representative of the position of the energy barycenter of each of the two light images ( synchronization means ( means (
