Abstract
The device for the measurement of distances and of the angle of incidence of a light beam comprises an optical emitting system in order to project the light beam onto the object to be measured, and an optical receiving system in order to project the reflected light onto position detectors. The optical receiving system comprises two prisms which refract the reflected light beam with an angular compression and expansion, respectively, thus allowing to reduce the dimensions and the sensitivity of a detector for the measurement of a given measuring range.
