摘要： This disclosure provides systems, methods and apparatus for illumination, such as for illuminating displays, including reflective displays. An illumination device may include a light-extracting, diffusive holographic medium. The holographic medium may be a holographic film and may be disposed on the surface of a light guide, and includes a hologram that both extracts light out of the light guide and diffuses this extracted light for propagation towards the display elements of the display. The hologram can extract light by redirecting light, which is propagating within the light guide, so that the light propagates out of the light. The diffusion occurs upon the light being redirected, as the hologram redirects the light towards the light guide in a controlled range of angles.

摘要： Several unique configurations for interferometric recording of volumetric phase diffractive elements with relatively high angle diffraction for use in waveguides are disclosed. Separate layer EPE and OPE structures produced by various methods may be integrated in side-by-side or overlaid constructs, and multiple such EPE and OPE structures may be combined or multiplexed to exhibit EPE/OPE functionality in a single, spatially-coincident layer. Multiplexed structures reduce the total number of layers of materials within a stack of eyepiece optics, each of which may be responsible for displaying a given focal depth range of a volumetric image. Volumetric phase type diffractive elements are used to offer properties including spectral bandwidth selectivity that may enable registered multi-color diffracted fields, angular multiplexing capability to facilitate tiling and field-of-view expansion without crosstalk, and all-optical, relatively simple prototyping compared to other diffractive element forms, enabling rapid design iteration.

摘要： A method of digitally processing light waves passing through a planar structure having given functions fin(x, y, ω) and fout(x, y, ω) and consisting of a light-propagating and distributing layer. This layer contains a plurality of interconnecting pattern elements of a holographic pattern and a plurality of planar optical elements arranged in a predetermined pattern on the aforementioned light-propagating and distributing layer. The method consists of calculating positions and shapes of the interconnecting pattern elements of the holographic pattern based on the aforementioned given functions by solving an inverse problem. The interconnecting pattern elements have refractive indices different from the refractive indices of the light-propagating and distributing layer and are manufactured on the basis of the results of the calculations. The aforementioned continuous function is digitized, and the obtained digitized planar holographic pattern is used for converting the function fin(x, y, ω) into the function fout(x, y, ω).
