Abstract
Cet appareil de projection omnidirectionnel (130) est destiné à capter une image d'une scène sensiblement hémisphérique, à partir d'un unique point de vue, et il comprend un réflecteur (135) sensiblement paraboloïde, convexe, tronqué et placé pour réfléchir de manière orthographique une image d'une scène sensiblement hémisphérique, ainsi qu'un capteur (110) d'images disposé pour recevoir l'image réfléchie de manière orthographique. On décrit un appareil de projection omnidirectionnel destiné à projeter une image d'une scène sensiblement hémisphérique telle que vue depuis un unique point de vue, cet appareil comprenant des moyens de projeter un faisceau collimaté de lumière modulée avec l'image, ainsi qu'un réflecteur sensiblement paraboloïde, convexe, tronqué et placé pour réfléchir de manière orthographique le faisceau collimaté de lumière modulée avec l'image, pour projeter la scène hémisphérique.
