Abstract
A head-mounted light field display device, the device comprising at least one multiplexed light field display module adapted to face an eye of a viewer wearing the device, the multiplexed light field display module comprising a light field view image generator and a waveguide with a set of shutters, the light field view image generator operable to generate, over time, a set of beams of light from a different one of a set of light field view images, the shuttered waveguide operable to transmit the set of beams and to open, over time, a different subset of the set of shutters, the subset corresponding to a position associated with the view image, thereby to emit the set of beams via the subset, thereby to display to the viewer a time-varying optical light field representative of the set of view images.
Claims19
A head-mounted light field display device, the device comprising at least one at least partially transparent multiplexed light field display module adapted to face at least one eye of a viewer wearing the device, the multiplexed light field display module comprising a light field view image generator, a waveguide comprising a set of first shutters spatially distributed along its length, the light field view image generator operable to generate, over time, a set of beams of light from a different one of a first set of light field view images, the waveguide operable to transmit the set of beams along its length and past any closed first shutters, and to open, over time, a different subset of the set of first shutters, the subset of the set of first shutters corresponding to a position associated with the view image, thereby to emit the set of beams via the subset of the set of first shutters, thereby to display to the viewer a time-varying optical light field representative of the first set of view images.
