Abstract

L'invention concerne un module optique pour affichage d'image stéréoscopique multivue, un dispositif d'affichage qui utilise ce module optique et un procédé associé. Le module optique de l'invention comprend un PBS servant à passer P composante d'onde d'un faisceau d'entrée et à réfléchir S composante d'onde du faisceau d'entrée, des premier et second diviseurs de faisceau qui divisent les faisceaux provenant du PBS en plusieurs trajets, ainsi qu'une pluralité de CLS (de préférence, quatre) pour réfléchir les faisceaux des premier et second diviseurs de faisceau et afficher respectivement chaque ensemble de données d'image 2D avec un point de vue différent (de préférence, quatre). Le dispositif d'affichage d'image stéréoscopique comprend un écran, un module optique et une lentille de projection pour agrandir les faisceaux de sortie provenant du module optique et projeter les faisceaux ainsi agrandis sur l'écran. Selon l'invention, la projection de plus d'un point de vue sur l'écran permet d'afficher une image stéréoscopique plus naturelle et plus expressive.
