Abstract

La présente invention concerne un dispositif de projection de type à balayage (PJ) dans lequel une lumière émise par une source lumineuse (1) est défléchie de manière bidimensionnelle par un élément de déflexion (3) et projetée obliquement par l'intermédiaire d'un système optique de projection (7) sur un écran (SC). Le système optique de projection (7) a une pluralité de surfaces de réflexion (S5, S8) et une surface de réfraction (S6). En déterminant de manière appropriée la forme surfacique de chacune des surfaces optiques du système optique de projection (7), la surface de réflexion (S8) disposée le plus près de l'écran (SC) peut avoir la fonction de corriger une distorsion trapézoïdale et la surface de réfraction (S6) peut avoir la fonction de corriger une déformation de surface d'image. Ainsi, il est possible de réduire toute la taille du dispositif de projection de type à balayage (PJ) qui effectue une projection oblique et de corriger de préférence à la fois la distorsion trapézoïdale et la déformation de surface d'image, formant de ce fait une image préférable sur tout l'écran.
