Title (EN) NEAR EYE 3D DISPLAY WITH SEPARATE PHASE AND AMPLITUDE MODULATORS
(FR) DISPOSITIF D'AFFICHAGE 3D PROCHE DE L’ŒIL ÉQUIPÉ DE MODULATEURS DE PHASE ET D'AMPLITUDE SÉPARÉS
Abstract:
(EN) Augmented reality glasses include near eye displays the include sources of imagewise amplitude modulated light optical coupled to spatial phase modulators or active zone plate modulators and optically coupled to eye coupling optics. The sources of imagewise amplitude modulated light can include emissive 2D display panels or light sources coupled to imagewise amplitude modulators. The eye coupling optics can include volume holographic diffraction gratings.
(FR) La présente invention concerne des lunettes à réalité augmentée comprenant des dispositifs d'affichage proches de l’œil qui comportent des sources d'optique de lumière modulée en amplitude d'image couplées à des modulateurs de phase spatiaux ou à des modulateurs de plaque de zone active et couplées optiquement à des optiques de couplage oculaire. Les sources de lumière modulée en amplitude d'image peuvent comprendre des panneaux d'affichage 2D émissifs ou des sources lumineuses couplées à des modulateurs d'amplitude d'image. L'optique de couplage oculaire peut comprendre des réseaux de diffraction holographiques volumiques.
