Abstract

Un mode de réalisation représentatif de présente invention concerne un système de réalité virtuelle pour l'affichage d'une image stéréoscopique centrée sur un téléspectateur. Ce système représentatif comporte des premier et second affichages disposés autour d'un axe à un angle d'orientation d'au moins environ 90° l'un par rapport à l'autre. Un filtre polarisant est adjacent à chacun des premier et second affichages. Un demi-miroir est disposé autour d'un axe et divise plus ou moins en deux parties égales l'angle d'orientation. Le demi-miroir présente une largeur et une hauteur, dont au moins une est au moins supérieure de 10 % à une largeur et une longueur correspondante des premier et deuxième affichages.
