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: The present disclosure describes near-eye display systems including an array of projectors and a one-dimensional exit pupil expander. The array of projectors can be arranged along a first dimension and can output image light towards an input coupler within a waveguide that provides one-dimensional exit pupil expansion. In some implementations, arrays of monochromatic projectors are implemented and arranged in offset columns. The input coupler in-couples the image light from the array of projectors into a TIR path within the waveguide. Different optical elements, including diffractive and reflective optics, may be implemented as the input coupler. The image light travels within the waveguide until it interacts with an output coupler. Upon interaction with the output coupler, the image light is expanded in a second dimension transverse to the first dimension and is coupled out of the waveguide.

Abstract: This document relates to head mounted display devices. One example can include a housing configured to be positioned relative to a head and eye of a user and a transparent visual assembly positioned by the housing in front of the user's eye and comprising multiple eye tracking illuminators distributed across the transparent visual assembly and configured to emit non-visible light and multiple eye tracking detectors distributed across the transparent visual assembly and configured to detect the non-visible light reflected back from the eye of the user.

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.
