Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

A display may include a waveguide, a diffractive input coupler, and an output coupler. The input coupler may diffract image light into the waveguide. The output coupler may diffract the image light out of the waveguide and towards an eye box. The output coupler may include a first volume hologram with a first grating vector and a second volume hologram with a second grating vector. The first and second grating vectors may be oriented at the same angle from opposing sides of an axis. The input coupler may have a first pitch. The first and second volume holograms may have a second pitch. The second pitch may be constant across the output coupler. In order to mitigate dispersion by the input coupler, the second pitch may be equal to twice the first pitch times a cosine of the angle.

A skew mirror is an optical reflective device whose reflective axis forms a non-zero angle with the surface normal. A spatially varying skew mirror is a skew mirror whose reflective axes vary as a function of lateral position. If a spatially varying skew mirror was subdivided into many pieces, some or all of the many pieces could have a reflective axis that points in a different direction. In some variations, a spatially varying skew mirror can act as a focusing mirror that focuses incident light. A spatially varying skew mirror can be made by recording interference patterns between a phase-modulated writing beam and another writing beam or by recording interference patterns between planar wavefronts in a curved holographic recording medium that is later bent or warped.

Disclosed are relay elements exhibiting transverse localization. The relay elements may include a relay element body having one or more structures, where the structures can be coupled in series, in parallel and/or in stacked configurations. The structures may have multiple surfaces such that energy waves propagating therethrough the relay elements may experience spatial magnification or de-magnification.

A camera device having an enlarged or wide-angle field of view generates images of surroundings simultaneously using only one image capturing unit, such as an image sensor, for example. The camera device uses a diverting unit disposed upstream of the image capturing unit. The diverting unit includes so-called holographic optical elements which, based on their deflection structures, divert or deflect light so that the camera device can capture the wide-angle field of view, without generating imaging aberrations on the resulting image(s). The deflection structures are wavelength-selective and/or angle-selective. The total field of view is subdivided into individual angle-of-incidence regions by virtue of the properties of the deflection structures.

Disclosed are systems and methods for manufacturing energy relays for energy directing systems and Transverse Anderson Localization. Systems and methods include providing first and second component engineered structures with first and second sets of engineered properties and forming a medium using the first component engineered structure and the second component engineered structure. The forming step includes randomizing a first engineered property in a first orientation of the medium resulting in a first variability of that engineered property in that plane, and the values of the second engineered property allowing for a variation of the first engineered property in a second orientation of the medium, where the variation of the first engineered property in the second orientation is less than the variation of the first engineered property in the first orientation.

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.

An optical device includes a first polarization selective reflector; a second polarization selective reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs first light toward the second polarization selective reflector and the second polarization selective reflector directs at least a portion of the first light toward the first polarization selective reflector as second light. The optical device includes a first reflector positioned relative to the first polarization selective reflector so that the first polarization selective reflector directs at least a portion of the second light received from the second polarization selective reflector toward the first reflector as third light and the first reflector directs at least a portion of third light toward the first polarization selective reflector.

Energy systems are configured to direct energy according to a four-dimensional (4D) plenoptic function. In general, the energy systems include a plurality of energy devices, an energy relay system having one or more relay elements arranged to form a singular seamless energy surface, and an energy waveguide system such that energy can be relayed along energy propagation paths through the energy waveguide system to the singular seamless energy surface or from the singular seamless energy surface through the energy relay system to the plurality of energy devices.

Methods, systems and computer program products for displaying an augmented image using a holographic object via a mobile device are provided. Aspects include receiving, by a processor of the mobile device while displaying an image on a display screen of the mobile device, a user input. Aspects also include identifying a portion of the image based on the user input. Aspects further include outputting, by a holographic module of the mobile device, one or more dynamic holographic objects in three-dimensional space above the display screen, wherein the one or more dynamic holographic objects are determined at least in part based on the portion of the image identified.
