Title (EN) MULTIPLE PASS OPTICAL SYSTEM
(FR) SYSTEME OPTIQUE A PASSAGE MULTIPLE
Abstract: front page image
(EN)A multiple pass optical system has two plane mirrors (10, 11) opposing one another with two biprism elements (12, 13) located in between. The biprism elements (12, 13) are arranged to define in combination with the plane mirrors (10, 11) a plurality of beam paths having a common point of intersection (2). In this way with a minimum number of optical elements a system is provided with angularly multiplexed beam paths which spatially overlap in one plane.
(FR)L'invention concerne un système optique à passage multiple doté de deux miroirs plan (10, 11) qui se font face, et entre lesquels se trouvent deux éléments biprismes (12, 13). Ces éléments (12, 13) sont disposés de manière à définir, en combinaison avec les miroirs plan (10, 11), une pluralité de trajets de faisceau ayant un point d'intersection commun (2). Dans une telle configuration, avec un nombre minimum d'éléments optiques, on dispose d'un système ayant des trajets de faisceau à multiplexage angulaire qui se chevauchent spatialement dans un plan.
