Abstract

L'invention concerne un système optique utilisé dans des afficheurs à projection, qui comporte plusieurs sources lumineuses monoblocs associées à plusieurs émetteurs hyperboliques composites à base de réflexion, un dispositif à base de filtre dichroïque gradué destiné à homogénéiser la sortie lumineuse desdites sources lumineuses monoblocs, un dispositif à semi-conducteurs à cristaux liquides ferroélectriques destiné à l'éclairage avec sortie lumineuse à partir d'un réseau de sources lumineuses monoblocs, et un diffuseur de polarisation conçu pour l'homogénéisation de la lumière au niveau du dispositif à semi-conducteurs à cristaux liquides ferroélectriques, le diffuseur de polarisation étant placé en un point de l'espace, dans le système optique, et la dimension d'un faisceau lumineux émis à partir du dispositif à base de filtre dichroïque gradué étant sensiblement maximale.
