Abstract

L'invention porte sur un dispositif d'affichage d'image tridimensionnelle utilisant deux miroirs (paraboloïdaux) asphériques, ce dispositif étant utilisé dans la formation d'une image tridimensionnelle d'un objet. Le dispositif possède deux miroirs paraboloïdaux opposés, les axes optiques des miroirs coïncidant. Le sommet du second miroir paraboloïdal coïncide avec un point focal du premier, et l'objet est placé autour du sommet du second miroir paraboloïdal de sorte que l'image réelle de l'objet puisse être observée par l'orifice du premier miroir paraboloïdal. Lorsque la longueur focale du premier miroir paraboloïdal est identique à celle du second miroir, l'image réelle se forme autour du sommet du premier miroir. Lorsqu'une longueur focale du premier miroir est plus courte que celle du second miroir, l'image réelle de l'objet se forme à l'écart du sommet du premier miroir paraboloïdal.
