Abstract

[Affichage transparent Un dispositif optique comprend un guide d’onde transparent (102), présentant une première portion d’expansion (202) ; une deuxième portion d’expansion (204), reliée à la première portion d’expansion (202), la deuxième portion d’expansion (204) comprend une zone de sortie de guide (216) ; une source de rayonnements lumineux (104) comprenant au moins deux sources lumineuses (1081, 1082, 1083) dirigées de manière à émettre un rayonnement lumineux respectif (2201, 2202, 2203) dans la première portion d’expansion (202), les sources lumineuses (1081, 1082, 1083) éclairant le guide d’onde transparent (102) ; et un élément optique holographique (106), disposé sur la deuxième portion d’expansion (204) et agencé pour diffuser le rayonnement (2201, 2202, 2203) qui sort du guide d’onde (102). Figure pour l’abrégé : Fig. 1][Transparent display An optical device comprises a transparent waveguide (102), having a first expansion portion (202); a second expansion portion (204), connected to the first expansion portion (202), the second expansion portion (204) comprises a guide exit zone (216); a source of light radiation (104) comprising at least two light sources (1081, 1082, 1083) directed so as to emit respective light radiation (2201, 2202, 2203) in the first expansion portion (202), the sources light (1081, 1082, 1083) illuminating the transparent waveguide (102); and a holographic optical element (106), arranged on the second expansion portion (204) and arranged to diffuse the radiation (2201, 2202, 2203) which exits the waveguide (102).
