Abstract

L'invention concerne un élément mince de sécurité optique comprenant une surface de réorientation de lumière réfléchie ou réfractée présentant un motif en relief utilisable pour réorienter la lumière incidente en provenance d'une source de lumière et former une image projetée sur une surface de projection, l'image projetée comprenant un motif caustique reproduisant un motif de référence qui est facilement reconnaissable visuellement par une personne. L'invention concerne également un procédé de conception d'un motif en relief d'une surface de réorientation de lumière d'un élément mince de sécurité optique.
