Abstract

L'invention concerne un système de projection à l'aide de sources d'illumination cohérentes, doté d'un organe générateur d'image (1K, 2K) pouvant comprendre une matrice (1, 1V) de préférence un modulateur spatial de lumière (SLM), doté de modulateurs de lumière pour pixels de couleur (1R, 1G, 1B), plusieurs fenêtres (88) à éléments dispersifs étant disposées à proximité de l'organe générateur d'image (1K, 2K), et une dispersion optique avec une déviation standard (DV) pouvant être assurée au moyen d'une tension alternative (VA) superposée sur une tension d'alimentation (VD) sur la fenêtre.
