Abstract: A color correction mask programmatically generated in software on an HMD device is applied to a gaze region on a display field of view (FOV) on a head-mounted display (HMD) device to optimize system resources while rendering a display. Eye monitoring sensors are utilized to track movement of a user's eyes while the user operates the HMD device to determine a gaze position of the user's eyes on the display FOV. Using the determined gaze position, a dynamic foveal gaze region is sized around the gaze position so that the foveal portion of the display FOV is color-corrected, that is, color non-uniformities are reduced or eliminated. In other implementations, a gaze-based weighting mode is implemented in which measurements of the user's full eye or eye orbit are utilized to color correct a larger surface area of the display FOV relative to the foveal color correction mode.

Abstract: A wearable image display system includes a headpiece, a first and a second light engine, and a first and a second optical component. The first and second light engines generate a first and a second set of beams respectively, each beam substantially collimated so that the first and second set form a first and a second virtual image respectively. Each optical component is located to project an image onto a first and a second eye of a wearer respectively. The first and second sets of beams are directed to incoupling structures of the first and second optical components respectively. Exit structures of the first and second optical components guide the first and second sets of beams onto the first and second eyes respectively. The optical components are located between the light engines and the eyes. Both of the light engines are mounted to a central portion of the headpiece.

Abstract: A near-eye optical display system utilizes a compact display engine that couples image light from an imager to a waveguide-based display having diffractive optical elements (DOEs) that provide exit pupil expansion in two directions. The display engine comprises a pair of single axis MEMS (Micro Electro Mechanical System) scanners that are configured to reflect the image light through horizontal and vertical scan axes of the display system's field of view (FOV) using raster scanning. The MEMS scanners are arranged with their axes of rotation at substantially right angles to each other and operate with respective quarter wave retarder plates and a polarizing beam splitter (PBS) to couple the image light into an in-coupling DOE in the waveguide display without the need for additional optical elements such as lenses or relay systems.

Abstract: An input-coupler of an optical waveguide includes one or more Bragg polarization gratings for coupling light corresponding to the image in two different directions into the optical waveguide. The input-coupler splits the FOV of the image coupled into the optical waveguide into first and second portions by diffracting a portion of the light corresponding to the image in a first direction toward a first intermediate component, and diffracting a portion of the light corresponding to the image in a second direction toward a second intermediate component. An output-coupler of the waveguide combines the light corresponding to the first and second portions of the FOV, and couples the light corresponding to the combined first and second portions of the FOV out of the optical waveguide so that the light corresponding to the image and the combined first and second portions of the FOV is output from the optical waveguide. The input-coupler splitting the light to two or more intermediate components provides an increased FOV.

Abstract: An apparatus for use in replicating an image associated with an input-pupil to an output-pupil includes a planar optical waveguide including a bulk-substrate, and also including an input-coupler, an intermediate-component and an output-coupler. The input-coupler couples light corresponding to the image into the bulk-substrate and towards the intermediate-component. The intermediate-component performs horizontal or vertical pupil expansion and directs the light corresponding to the image towards the output-coupler. The output-coupler performs the other one of horizontal or vertical pupil expansion and couples light corresponding to the image, which travels from the input-coupler to the output-coupler, out of the waveguide. The apparatus further includes an adjacent planar optical component to provide a more uniform intensity distribution compared to if the adjacent planar optical component were absent.

Abstract: In implementations of hologram focus accommodation, a focus accommodation system is implemented for variable focus of a generated image, such as a hologram, that is displayed for viewing on a waveguide display. The focus accommodation system includes switchable polarization retarders that rotate a polarization of light of the generated image, where the light passes through the switchable polarization retarders along an imaging path in which the generated image is viewable. The focus accommodation system also includes polarization sensitive gratings alternatingly interspersed with the switchable polarization retarders. Each of the polarization sensitive gratings are configurable to diffract the light in a first polarization state and transmit the light in a second polarization state. The variable focus is adjustable to a focal distance at which a user perceives viewing the generated image as displayed by the waveguide display.
