Abstract

La présente invention concerne un système d'imagerie intégrale réfléchissant à double vue et fournit une image tridimensionnelle à l'aide d'un projecteur unique et d'un réseau de miroirs. Un système d'affichage à double vue restaure deux images tridimensionnelles différentes dans deux zones de visualisation séparées, et un observateur de chaque zone de visualisation peut voir une image tridimensionnelle différente. La présente invention présente des effets remarquables : être utilisable en tant que grand écran, ne pas gêner visuellement, et permettre un affichage à double vue tridimensionnel ne nécessitant pas de dispositif supplémentaire tel que des lunettes à obturateur.
