Abstract: Optical systems including an interferometer utilizing a spatial light modulator. A light guide including a first beam splitter and multiple mirrors directs incoherent light through the beam splitter to the interferometer to generate an interference light pattern, and further directs the interference light pattern back to the first beam splitter via the mirrors.

Abstract: The computational scaling challenges of holographic displays are mitigated by techniques for generating holograms that introduce foveation into a wave front recording planes approach to hologram generation. Spatial hashing is applied to organize the points or polygons of a display object into keys and values.
