Abstract

L'invention concerne un dispositif dans lequel le faisceau lumineux du projecteur, se propageant de façon pratiquement parallèle à la surface d'image, présente une compression anamorphotique qui comprime fortement ledit faisceau dans une dimension perpendiculaire à la surface d'image. Un miroir légèrement parabolique d'un seul côté, situé au bord de la surface d'image, renvoie ensuite l'image vers elle-même. La compression anamorphotique est ainsi compensée par l'angle d'incidence aigu de la lumière sur la surface d'image.
