    Abstract: A multi-optical surface optical design for generating multiple focal planes with identical image data displayed at substantially the same time to generate the perception of varying focal depths is described. The multi-optical surface optical design can include a device comprising reflective optical surfaces that can be arranged on top of one another and configured to generate multiple focal planes and an image source for projecting image data onto the reflective optical surfaces. The technologies described can cause image data to be rendered in a focal plane corresponding to a desired focal distance and multiple copies of the image can be perceived in other focal planes of the multiple focal planes at substantially the same time as the image data is rendered in the focal plane. Each copy of the multiple copies can be presented with a perceived degree of sharpness such that each copy is out-of-focus.

    Abstract: Examples are disclosed herein relating to an adjustable scanning system configured to adjust light from an illumination source on a per-pixel basis. One example provides an optical system including an array of light sources, a holographic light processing stage comprising, for each light source in the array, one or more holograms configured to receive light from the light source and diffract the light, the one or more holograms being selective for a property of the light that varies based upon the light source from which the light is received, and a scanning optical element configured to receive and scan the light from the holographic light processing stage.

    Abstract: A head-mounted display device comprises a rendering engine configured to generate a hologram representative of a three-dimensional object. The hologram includes depth information that causes the three-dimensional object to be rendered with a focus that is determined by the depth information. The device also includes a spatial light modulator that modulates light from a light source as indicated by the hologram. A switchable hologram comprises multiple stacked switchable gratings. Each of the stacked switchable gratings is associated with one or more resulting exit pupil locations on a viewing surface. The system also comprises an eye tracker configured to map a viewing direction of a user's eye to a viewing location on the viewing surface. A processor is configured to activate a particular switchable grating within the switchable transmission hologram that is associated with an exit pupil location that aligns with the viewing location.

    Abstract: A light engine comprises a liquid crystal on silicon (LCOS) panel that is operated in combination with illumination and imaging optics to project high-resolution virtual images into a waveguide-based exit pupil expander (EPE) that provides an expanded exit pupil in a near-eye display system. In an illustrative example, the illumination optics comprise a laser that produces illumination light that is reflected by a MEMS (micro-electromechanical system) scanner using raster scanning to post-scan optics including a microlens array (MLA) and one or more collimating or magnifying lenses before impinging on the LCOS panel. The LCOS panel operates in reflection in combination with imaging optics, including one or more of beam-steering mirror and beam splitter, to couple virtual image light from the LCOS panel into the EPE.

    Abstract: Examples are disclosed that relate to holographic near-eye display systems. One example provides a near-eye display device, comprising a diverging light source, an image producing dynamic digital hologram panel configured to receive light from the diverging light source and form an image. The near-eye display device also includes and a combiner comprising a holographic optical element positioned to receive light from the dynamic digital hologram panel and to redirect the light toward an eyebox, the holographic optical element being positioned between the eyebox and a view of an external environment to combine a view of the image formed by the dynamic digital hologram panel and the view of the external environment.
