Abstract

Un appareil d'imagerie (100) fournit une image provenant d'un affichage (106) à un observateur (101). Il comprend un affichage produisant une sortie optique, une surface d'affichage (109) conçue et fabriquée pour être regardée par l'observateur, et un ensemble miroir de balayage/lentille (102) intercalé du point de vue optique entre l'afficheur et la surface d'affichage et conçu et construit de façon à scanner l'affichage de manière répétitive et alternative, à produire une image scannée et à la transmettre vers la surface d'affichage, ce qui permet de la regarder. On décrit plusieurs conceptions et sous-ensembles d'affichage pour émission à effet de champ de terrain que l'on peut employer utilement dans un tel appareil d'imagerie.
