Abstract

Un affichage tridimensionnel comprend (a) une pluralité d'écrans commutables (2a-e) agencés les uns derrière les autres, chaque écran étant commutable indépendamment entre un état de haute dispersion et un état transparent, (b) un moyen de projection (3) destiné à projeter une séquence d'images, chaque image se trouvant dans la séquence correspondant à un des écrans commutables et faisant partie d'une image tridimensionnelle globale, et (c) un moyen de commutation synchronisée (4) destiné à commuter chaque écran commutable de manière synchrone avec la projection de la séquence d'images par le moyen de projection, de manière qu'un écran commutable particulier se trouve dans son état de haute dispersion lorsque l'image lui correspondant est projetée, et dans son état transparent au moins lorsque l'image correspondant à un autre écran est projetée, l'écran particulier étant positionné entre cet autre écran et soit le projecteur soit le spectateur.
