CA 2136777

A picture display apparatus which converts an input optical image into a projected picture using a photoelectric effect. The picture display apparatus includes an image transfer device having a plurality of graded index lenses which are bundled in parallel to an optical axis. The image transfer device is provided between an electro-optical device and a picture display device so that an input optical image on the picture display device is transferred in equisize onto the photoconductive layer of the electro-optical device.

L'invention est un appareil d'affichage d'images qui convertit un signal lumineux en une image projetée à l'aide de l'effet photoélectrique. L'appareil d'affichage d'images de l'invention comprend un dispositif de transfert d'images ayant une pluralité de lentilles à gradient d'indice de réfraction qui sont groupées en parallèle sur un axe optique. Ce dispositif de transfert d'images est installé entre un dispositif électro-optique et le dispositif d'affichage d'images de sorte que l'image affichée est transférée avec les mêmes dimensions sur la couche photoconductrice du dispositif électro-optique.
