摘要： 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.
