Title (EN) HOLOGRAPHIC DISPLAY
(FR) DISPOSITIF D'AFFICHAGE HOLOGRAPHIQUE
Abstract:
(EN) This invention generally relates to displaying a substantially two-dimensional input image, and is particularly applicable for use in a head-up display. Display apparatus for displaying a substantially two-dimensional input image comprises: a first spatial light modulator configured to form a hologram on the basis of a first drive signal to phase modulate a beam of substantially coherent light; a second spatial light modulator comprising a plurality of pixels, the pixels configured to selectively amplitude modulate on the basis of a second drive signal the light modulated by the first spatial light modulator; and a controller configured to generate said second drive signal on the basis of said input image.
(FR) Cette invention porte de manière générale sur l'affichage d'une image d'entrée sensiblement en deux dimensions, et, est particulièrement applicable à l'utilisation dans un dispositif d'affichage tête haute. Un appareil d'affichage pour afficher une image d'entrée sensiblement en deux dimensions comprend : un premier modulateur spatial de lumière configuré pour former un hologramme sur la base d'un premier signal de commande pour moduler en phase un faisceau de lumière sensiblement cohérente ; un second modulateur spatial de lumière comprenant une pluralité de pixels, les pixels étant configurés pour moduler en amplitude de façon sélective, sur la base d'un second signal de commande, la lumière modulée par le premier modulateur spatial de lumière ; et un dispositif de commande configuré pour générer ledit second signal de commande sur la base de ladite image d'entrée.
