Abstract

The invention relates to a device for measuring distances, in particular of the contactless type. In order to avoid errors and inaccuracies in the measurement due to the shape of the surfaces S of objects being measured, their chromatic features and the variations in response of the device due to thermal effects, the invention envisages a measuring device comprising a device 1 emitting a beam I of electromagnetic rays suitably modulated and directed against the surface S being measured and a receiver 4 for detecting the reflected beam R. The measurement of the distance is determined in a suitable processing circuit by the phase difference between the modulation signal of the incident beam I and the reception signal corresponding to the reflected beam R. <IMAGE>
