Abstract

La présente invention concerne un appareil de projection optique, un procédé et un système de projection utilisant l'appareil de projection optique et au moins un ou plusieurs dispositifs pour fournir des données d'image interne(s) et / ou externe(s). L'appareil de projection optique 101 du système de projection comprend une unité de formation d'image et une unité optique; dans lequel une unité de formation d'image génère une image à projeter par le biais d'une unité optique, caractérisé en ce que l'unité de formation d'image et l'unité optique sont configurées et agencées de sorte qu'une projection asymétrique de l'image 105 par rapport à l'axe optique de l'unité optique soit obtenue, dans lequel l'image projetée dispose d'une largeur et d'une hauteur et dans lequel la projection asymétrique fait référence à un décalage de l'image projetée à la fois dans les directions de la largeur et de la hauteur de l'image projetée par rapport à l'axe optique de l'unité optique.
