CA 2522616

An optical system for use in projection based displays includes a plurality of solid state light sources associated with a plurality of total internal reflection based compound hyperbolic emitters, a graduated dichroic filter based device for homogenizing light output from the plurality of solid state light sources, a ferroelectric liquid crystal on silicon device for illumination with light output from the array of solid state light sources, and a polarization diffuser for homogenization of light at the ferroelectric liquid crystal on silicon device, wherein the polarization diffuser is positioned at a point in space, in the optical system, where the size of a beam of light transmitted from the graduated dichroic filter based device is substantially at a maximum.

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.
