Title (EN) HOLOGRAPHIC WIDE FIELD OF VIEW DISPLAY
(FR) AFFICHAGE HOLOGRAPHIQUE À CHAMP DE VISION LARGE
Abstract:
(EN) A head-mounted display device comprises a rendering engine configured to generate a hologram representative of a three-dimensional object. The hologram includes depth information that causes the three-dimensional object to be rendered with a focus that is determined by the depth information. The device also includes a spatial light modulator that modulates light from a light source as indicated by the hologram. A switchable hologram comprises multiple stacked switchable gratings. Each of the stacked switchable gratings is associated with one or more resulting exit pupil locations on a viewing surface. The system also comprises an eye tracker configured to map a viewing direction of a user's eye to a viewing location on the viewing surface. A processor is configured to activate a particular switchable grating within the switchable transmission hologram that is associated with an exit pupil location that aligns with the viewing location.
(FR) Selon l'invention, un dispositif visiocasque comprend un moteur de rendu configuré pour produire un hologramme représentatif d'un objet tridimensionnel. L'hologramme comprend des informations de profondeur qui provoquent le rendu de l'objet tridimensionnel avec une mise au point qui est déterminée par les informations de profondeur. Le dispositif comprend également un modulateur spatial de lumière qui module la lumière provenant d'une source de lumière selon une indication par l'hologramme. Un hologramme commutable comprend de multiples réseaux commutables empilés. Chacun des réseaux commutables empilés est associé à un ou plusieurs emplacements de pupille de sortie résultants sur une surface de visualisation. Le système comprend également un dispositif de suivi d'œil configuré pour mapper une direction de visualisation de l'œil d'un utilisateur avec un emplacement de visualisation sur la surface de visualisation. Un processeur est configuré pour activer un réseau commutable particulier à l'intérieur de l'hologramme de transmission commutable qui est associé à un emplacement de pupille de sortie qui s'aligne avec l'emplacement de visualisation.
