(FR) DISPOSITIFS D'AFFICHAGE AÉRIENS RÉTRO-RÉFLÉCHISSANTS AVANCÉS
Abstract
(EN) A superstereoscopic image retroreflecting display that enables the formation of a real image in free space includes a first light source that generates a first light output; a lenticular lens optically coupled to the first light source that, with the first light source, generates a first light output having viewing angle dependency; a first beam splitter module; and a retroreflector module opposite the first light source.
(FR) Selon la présente invention, un dispositif d'affichage rétro-réfléchissant d'image superstéréoscopique qui permet la formation d'une image réelle dans un espace libre comprend une première source de lumière qui génère une première sortie de lumière ; une lentille lenticulaire couplée optiquement à la première source de lumière, laquelle, au moyen de la première source de lumière, génère une première sortie de lumière ayant une dépendance d'angle de visualisation ; un premier module de diviseur de faisceau ; et un module de rétroréflecteur opposé à la première source de lumière.
