A system and method for generating compact light-field displays through varying optical depths provides digital content in a more effective and efficient manner. The system includes a field-evolving cavity with a cavity exit pupil, a relay mechanism, and a system enclosure with an enclosure exit pupil. The field-evolving cavity modifies the light-field displays before outputting the light-field displays with the cavity exit pupil. More specifically, the field-evolving cavity includes at least one display panel, which initially generates the light-field displays, and at least one optical-tuning mechanism, which subsequently modifies the light-field displays to varying optical depths. The system enclosure houses the field-evolving cavity and the relay mechanism. The relay mechanism directs the light-field displays from the cavity exit pupil to the enclosure exit pupil, which outputs the light-field displays to a user.

Three-dimensional (3D) electronic displays provide different 3D views and employ one or both of an array of multibeam diffraction gratings arranged in offset rows and light valves having color filters. The displays include a plate light guide configured to guide light beams at a non-zero propagation angle, a multibeam diffraction grating configured to couple out a portion of the guided light beams as a plurality of light beams having different principal angular directions representing the different 3D views, and light valves configured to modulate the differently directed, coupled-out light beams. The multibeam diffraction grating may be a member of the array arranged in offset rows and the display may further include light valves having color filters. Alternately, the light valves include color filters and the display may further include the array of multibeam diffraction gratings arranged in offset rows.

A display system for realizing concentric light field with monocular-to-binocular hybridization, and methods thereof. At least some embodiments include a display arranged to emit or transmit light rays based on image content from a content engine, and an optical subsystem arranged to configure the light rays into a concentric light field. The concentric light field provides a virtual image in a large, contiguous spatial region, such that each eye of the human viewer can detect monocular depth from the light field, to provide a large field of view.

A display device includes a transparent light guiding layer having a bottom face on which a light diffusing region is formed as a design, a retroreflective layer, a polarizing beam that allows light having a first polarization direction to pass therethrough, and an emission unit configured to emit into the light guiding layer the light having the first polarization direction, or light having a different second polarization direction. When light having the first polarization direction is emitted, light reflected by the light diffusing region passes through the polarizing beam splitter such that the design is viewable. When light having the second polarization direction is emitted, light reflected by the retroreflective layer passes through the polarizing beam splitter such that an aerial image of the design is viewable.

A holographic calling system can capture and encode holographic data at a sender-side of a holographic calling pipeline and decode and present the holographic data as a 3D representation of a sender at a receiver-side of the holographic calling pipeline. The holographic calling pipeline can include stages to capture audio, color images, and depth images; densify the depth images to have a depth value for each pixel while generating parts masks and a body model; use the masks to segment the images into parts needed for hologram generation; convert depth images into a 3D mesh; paint the 3D mesh with color data; perform torso disocclusion; perform face reconstruction; and perform audio synchronization. In various implementations, different of these stages can be performed sender-side or receiver side. The holographic calling pipeline also includes sender-side compression, transmission over a communication channel, and receiver-side decompression and hologram output.
