ABSTRACT:
An optical triangulation measuring device includes an emmiter that emits two alternating light beams with different wavelengths along the same path; a beam splitter; an optical separator that directs the alternating split beams towards the surfaces from which they are reflected; an optical combiner that collects the beams and directs them along a path; optronic sensors that receive two light images and to deliver a signal indicating the position of the energy barycenter a time synchronizer for the two alternating beams and the two images on the optronic sensors; and a processor for processing the signals from the optronic sensors in order to supply information relating to the position and inclination of the surface.
