A simulator for simulating the view of a scene from a predetermined observer station. An image is projected onto an array of back projection screens which are viewed through a concave mirror positioned such that light reflected by the mirror to a predetermined viewing station is collimated. An opaque object is positioned on or immediately in front of the mirror so as to cover a portion of the mirror. This enables portions of a mirror with poor optical qualities, such as occurs adjacent abutting edges of separate sections of the mirror, to be obscured from view so that they do not adversely affect the perceived quality of the viewed image.
L'invention concerne un simulateur, destiné à simuler une scène vue depuis un poste d'observation prédéfini. On projette une image sur un ensemble d'écrans de projection par transparence, vus à travers un miroir concave, placé de manière à collimater la lumière réfléchie par ce miroir vers un poste d'observation prédéfini. Un objet opaque est disposé sur ou devant ce miroir afin de recouvrir une partie de ce dernier. Les parties de ce miroir présentant une mauvaise qualité optique, par exemple les bords adjacents de différentes sections de ce miroir, peuvent ainsi cachées afin de ne pas nuire à la qualité de l'image perçue.
