Title
(EN) METHOD AND SYSTEM FOR THREE-DIMENSIONAL (3D) PROJECTION
(FR) PROCÉDÉ ET SYSTÈME POUR PROJECTION TRIDIMENSIONNELLE (3D)
Abstract
(EN)
A method and system are described for projecting stereoscopic images using circularly polarized light with at least one polarizer for limiting the amount of light or radiant energy reaching a projection lens system and associated optical elements, and system configurations are discussed with respect to desired performance characteristics.
(FR)
La présente invention concerne un procédé et un système pour projeter des images stéréoscopiques en utilisant de la lumière polarisée circulairement avec au moins un polariseur pour limiter la quantité de lumière ou d'énergie radiante atteignant un système de lentilles de projection et d'éléments optiques associés. On envisage différentes configurations de systèmes par rapport aux caractéristiques de performances souhaitées.
