Abstract

Un projecteur comprend une plaque à fibres optiques (1) dont les faces terminales d'entrée (2) des guides de lumière (3) sont situées dans le plan d'image originale (a-a), ainsi qu'une lentille de projection (8) dans le champ optique duquel se trouvent les faces terminales de sortie (9) des guides de lumière (3) de la plaque à fibres optiques (1). Sur le chemin du faisceau de lumière de chaque guide de lumière (3) de la plaque à fibres optiques (1) se trouve un système optique (10) destiné à concentrer les faisceaux de lumière en un flux de lumière et destiné à orienter ledit flux de lumière dans l'oculaire d'entrée (11) de la lentille de projection (8). Le système optique (10) comprend un focon (12), un lentille convergente (13) ainsi qu'une lentille de réfraction (14), ces éléments étant montés successivement le long du chemin du faisceau de lumière dans le guide de lumière (3). L'axe optique (O4-O4) de la lentille convergente coïncide avec l'axe optique (O10O1) du guide de lumière (3).
