Title (EN) AUGMENTED REALITY DISPLAY
(FR) AFFICHEUR À RÉALITÉ AUGMENTÉE
Abstract:
(EN) A display has an image projector projecting collimated image illumination along a projection direction, and an optical element having two major surfaces and containing partially reflective surfaces which are internal to the optical element, planar, mutually parallel and overlapping relative to the projection direction. Each ray of the collimated image illumination enters the optical element and is partially reflected by at least two of the partially reflective surfaces so as to be redirected to exit the first major surface along a viewing direction. An alternative implementation; a first reflection from one of the partially reflective surfaces redirects part of the image illumination rays so as to undergo total internal reflection at the major surfaces of the optical element. The rays are then redirected by further reflection from another of the partially reflective surfaces to exit the optical element along the viewing direction.
(FR) L'invention concerne un afficheur comprenant un projecteur d'image qui projette un éclairage d'image collimaté le long d'une direction de projection, et un élément optique comprenant deux surfaces principales et contenant des surfaces partiellement réfléchissantes qui sont internes à l'élément optique, planes, mutuellement parallèles et qui se chevauchant par rapport à la direction de projection. Chaque rayon de l'éclairage d'image collimaté pénètre dans l'élément optique et est partiellement réfléchi par au moins deux des surfaces partiellement réfléchissantes de façon à être redirigé pour sortir de la première surface principale le long d'une direction de visualisation. Dans une variante de mise en œuvre, une première réflexion depuis l'une des surfaces partiellement réfléchissantes redirige une partie des rayons d'éclairage d'image de façon à subir une réflexion interne totale au niveau des surfaces principales de l'élément optique. Les rayons sont ensuite redirigés par réflexion supplémentaire depuis une autre des surfaces partiellement réfléchissantes pour sortir de l'élément optique le long de la direction de visualisation.
