Abstract

Tête matricielle de routage de faisceaux lumineux à adressage fréquentiel. L'invention concerne un dispositif (FIG. 1) permettant de générer un faisceau lumineux matriciel (1) alimentant, p.ex., le dernier étage d'un équipement de vidéo projection numérique, à l'aide d'une combinaison de sources lumineuses (2), (3) et (4) de faible/moyenne puissance supportant les trois couleurs de base (le rouge, vert et le bleu), de type laser ou source au xénon, et de n x m miroirs (5) d'une certaine taille et forme définis en fonction de l'application visée, réalisant le filtrage fréquentiel approprié, lié à la construction du miroir. Le dispositif comporte un certain nombre de matrices (6), (7), (8) et (9) de miroirs/filtres alignés géométriquement, orientant et filtrant les faisceaux lumineux (10) dans le but de générer un élément matriciel/symbole (1) de projection. Le dispositif s'affranchit d'une fonction de balayage grâce à un codage fréquentiel de la position de chaque élément matriciel projeté. La commande numérique permet de contrôler l'allumage des sources lumineuses en fonction de la configuration de la matrice/symbole d'affichage recherché à un instant « t » donné. Cette élément matriciel/symbole sera balayé sur une surface de projection afin de générer une séquence d'image vidéo complexe. Le système sera appliqué, p.ex. au Cinéma Numérique très haut de gamme et au « Home Cinéma ».
