Abstract

Le domaine général de l'invention est celui des dispositifs de visualisation comportant au moins un projecteur d'images (1) comportant un afficheur (10), une optique de projection (11) et un écran de visualisation (13), l'image dudit afficheur étant projetée par l'optique de projection sur ledit écran de visualisation. Le dispositif de visualisation selon l'invention comporte des moyens permettant de contrôler le taux de transmission optique et le taux de diffusion optique dudit écran de visualisation de façon à le rendre totalement transparent ou totalement diffusant, l'image n'étant projetée que dans ce dernier cas.
