Abstract

L’invention concerne un dispositif réflecteur (100) qui comprend :- un support (300) ;- une source lumineuse (400) agencée pour émettre un faisceau lumineux principal ;- N miroirs (2001 à 200N), partiellement transparents, assemblés sur le support, et délimités par une face avant (201i) partiellement réfléchissante, et une face arrière (202i), les miroirs (2001 à 200N) sont agencés d’une première position à une Nième position, de sorte que le faisceau lumineux principal soit incident sur la face avant (201i) du miroir en première position, et interagit successivement, selon l’ordre, avec chaque miroir pour former un faisceau réfléchi par la face avant (201i) et un faisceau transmis par la face arrière (202i), le faisceau réfléchi par la face avant (201i) d’un miroir dans une position i résultant de la réflexion du faisceau transmis par la face arrière du miroir dans la position i-1. Figure pour l’abrégé : Figure 3 .
