摘要： A holographic energy system is operable to generate an output wavefront according to a complex amplitude function. The holographic energy system includes a continuous three-dimensional energy medium, an array of energy devices configured to output energy to interact with the continuous three-dimensional energy medium to define a hologram therein, and an electromagnetic (EM) energy source positioned to output coherent EM energy that is incident on the hologram in the continuous three-dimensional energy medium to generate an output wavefront.

摘要： Relay systems may be incorporated into optical systems to direct light from at least one image source to a viewing volume. Light from a plurality of image sources may be directed by relay systems to a viewing volume. Some light from the plurality of image sources may be occluded by an occlusion system to reduce undesirable artifacts in when the relayed light from the plurality of image sources are observed in the viewing volume.

摘要： Disclosed embodiments include an energy waveguide system having an array of waveguides and an energy inhibiting element configured to substantially fill a waveguide element aperture and selectively propagate energy along some energy propagation paths through the array of waveguides. In an embodiment, such an energy waveguide system may define energy propagation paths through the array of waveguides in accordance to a 4D plenoptic system. In an embodiment, energy propagating through the energy waveguide system may comprise energy propagation for stimulation of any sensory receptor response including visual, auditory, somatosensory systems, and the waveguides may be incorporated into a holographic display or an aggregated bidirectional seamless energy surface capable of both receiving and emitting two-dimensional, light field or holographic energy through waveguiding or other 4D plenoptic functions prescribing energy convergence within a viewing volume. The waveguides may include different structures configured for each or all sensory system or energy domain to direct energy through refraction, diffraction, reflection, or other approaches of affecting the propagation paths of energy.

摘要： Disclosed are high-density energy directing devices and systems thereof for two-dimensional, stereoscopic, light field and holographic head-mounted displays. In general, the head-mounted display system includes one or more energy devices and one or more energy relay elements, each energy relay element having a first surface and a second surface. The first surface is disposed in energy propagation paths of the one or more energy devices and the second surface of each of the one or more energy relay elements is arranged to form a singular seamless energy surface. A separation between edges of any two adjacent second surfaces is less than a minimum perceptible contour as defined by the visual acuity of a human eye having better than 20/40 vision at a distance from the singular seamless energy surface, the distance being greater than the lesser of: half of a height of the singular seamless energy surface, or half of a width of the singular seamless energy surface.
