Abstract

Dans un système de fluoroscopie d'images tridimensionnelles comprenant un moniteur (10) d'images tridimensionnelles et des lunettes (14) de fluoroscopie d'images tridimensionnelles, les lunettes (14) de fluoroscopie d'images tridimensionnelles ayant un obturateur (12) à cristaux liquides pour voir le moniteur (10) d'images tridimensionnelles par fluoroscopie, le système comprend un film (16) à lumière polarisée placé uniquement sur un côté verre d'oeil dans l'obturateur (12) à cristaux liquides des lunettes (14) de fluoroscopie d'images tridimensionnelles, et un autre film (18) à lumière polarisée d'un ensemble à usage classique pour les deux yeux sur une face avant du moniteur (10) d'images tridimensionnelles. Dans cette construction, la lumière incidente d'un objet non polarisé, en dépit du fonctionnement de l'obturateur (12) à cristaux liquides, pénètre par l'obturateur (12) à cristaux liquides et le film (16) à lumière polarisée du côté verre d'oeil, dans le cas d'une visualisation d'objets par fluoroscopie, excepté s'il s'agit d'un affichage sur le moniteur (10) d'images tridimensionnelles. Par conséquent, on ne constate pas de phénomène de scintillation indépendamment du fonctionnement de l'obturateur (12) à cristaux liquides, et l'on constate un effet supplémentaire, les images droite et gauche sur l'écran du moniteur (10) d'images tridimensionnelles ne sont pas mélangées l'une à l'autre, même si un utilisateur visualise par fluoroscopie le moniteur (10) d'images tridimensionnelles en position oblique, lorsqu'il porte les lunettes (14) de fluoroscopie d'images tridimensionnelles.
