Abstract: This document relates to an optical device that uses adaptive optics as part of an optical system. The adaptive optics can be used to correct light rays that correspond to a portion of an eye box based on information received from an eye-tracking unit, and can also correct for aberrations in the optics in the optical device. The adaptive optics include corrective elements that can be modified using modifying elements to correct the angle of light rays, such that rays associated with a specific pupil position and gaze direction of a user's eye can be made parallel and ensure a high quality image is viewed by the user.

Abstract: This document relates to an optical device using waveguide that can enable propagation of large field of view images by use of metasurfaces, without the necessity of increasing the reflective index associated with the waveguide. The metasurfaces can further provide image distortion correction to images to account for possible distortion introduced by an optical assembly. The metasurfaces can also be used to create a foveated image, in order to achieve a larger field of view for the image.

Abstract: A display device includes an array of light emitters and a mirror configured to reflect light from the light emitters toward an image plane. The display device further includes a controller configured to control the array of light emitters and the mirror to sweep the mirror through a range of angles, and selectively enable the light emitters during sweeping of the mirror. The selective enablement of light emitters, and the sweeping of the mirror, are configured to cause emitted light from the light emitters to project a plurality of pixels on/toward the image plane, with the pixels being spaced with a non-uniform resolution.

Abstract: Examples are disclosed that relate to using an array of hot mirrors in an eye-imaging system. One example provides a head-mounted display system, comprising a frame, an eye-imaging camera supported on the frame, a switchable hot mirror array comprising a plurality of switchable hot mirrors configured to direct light reflecting from an eye toward the eye-imaging camera, and a controller configured to control switching of a reflectivity of each of the plurality of switchable hot mirrors.

Abstract: This document relates to head mounted display devices. One example can include a layer of individually controllable pixels that can be energized to emit light and a layer of lenses that are physically aligned over the pixels. The example can also include a layer of shutters interposed between the pixels and the lenses and configured to be independently transitioned between a transmissive state and an opaque state to limit paths of the emitted light that reach the layer of lenses.

Abstract: This document relates to head mounted display devices. In one example the head mounted display device includes a light engine including an array of individually controllable pixels that can be energized to emit light. The example also includes an optical assembly physically aligned with the light engine and including a set of focusing elements facing toward the light engine and a different set of focusing elements facing away from the light engine.
