Abstract

La présente invention concerne un élément de sécurité optique mince comprenant une surface de redirection de lumière réfléchissante ou réfractive présentant un motif en relief destiné à rediriger la lumière incidente provenant d'une source de lumière et former une image projetée sur une surface de projection, les paramètres optiques de cet élément de sécurité optique satisfaisant un critère de projection spécifique de telle sorte que l'image projetée comprenne un motif caustique reproduisant un motif de référence qui est facilement reconnaissable visuellement par une personne. La présente invention concerne également un procédé permettant de concevoir un motif en relief d'un élément de sécurité optique.
