Abstract

Le dispositif comporte une source 1 de lumière et un prisme droit 4 disposé sur le trajet du faisceau 2 émis par la source, la base de ce prisme étant polygonale et comprenant un nombre impair de cotés, ce prisme étant formé d'un matériau transparent à la lumière émise par la source. Application au balayage d'une surface d'une cible éloignée.The device comprises a light source 1 and a straight prism 4 arranged on the path of the beam 2 emitted by the source, the base of this prism being polygonal and comprising an odd number of sides, this prism being formed from a material transparent to the light emitted by the source. Application to the scanning of a surface of a distant target.
