Abstract

Agencement de projection et procédé destinés à la séparation de la lumière en pixels couleurs et entraînant un déplacement latéral de l'image projetée sur un écran (11). La lumière provenant de différentes couleurs, produite par des diodes laser (2), par exemple, est transmise à travers un dispositif de génération d'images (1K, 2K) et une lentille de projection (7). Le dispositif de génération d'images (1K, 2K) est de préférence un dispositif d'affichage à cristaux liquides du type à dispersion. Le déplacement latéral de l'image s'obtient par l'intermédiaire de microprismes, de microlentilles inclinées et/ou d'éléments de diffraction optiques situés du côté sortie du dispositif de génération d'images (1K, 2K) ou d'une lentille frontale désaxée.
