摘要： A transparent waveguide for use in eye tracking includes an input-coupler and an output-coupler. The input-coupler comprises a plurality of curved grating lines having a radially varying pitch. When positioned in front of an eye illuminated with infrared light, infrared light beams reflected from the eye and incident on the input-coupler enter the waveguide at the input-coupler, propagate through the waveguide by way of total internal reflections, and exit the waveguide proximate the output-coupler. The radially varying pitch of the curved grating lines of the input-coupler provides angular encoding of infrared light incident on the input-coupler, and more specifically, causes different beams of infrared light incident on respective different horizontal and vertical positions of the input-coupler to propagate through the waveguide at respective different angles of reflection and exit the waveguide at respective different angles of incidence relative to a surface of the waveguide through which infrared light beams exit.

摘要： Embodiments are disclosed for adjusting alignment of a near-eye optic of a see-through head-mounted display system. In one embodiment, a method of detecting eye location for a head-mounted display system includes directing positioning light to an eye of a user and detecting the positioning light reflected from the eye of the user. The method further includes determining a distance between the eye and a near-eye optic of the head-mounted display system based on attributes of the detected positioning light, and providing feedback for adjusting the distance between the eye and the near-eye optic.

For example, one disclosed embodiment provides, on a near-eye display device, a method comprising receiving an image of an eye from a camera via a reverse display optical path, detecting a location of the eye in the image, and determining a relative position of the eye with regard to a target viewing position of the near-eye display. The method further comprises determining an adjustment to make to the near-eye display device to align the location of the eye with the target viewing position.

摘要： A transparent waveguide, which is for use in tracking an eye that is illuminated by infrared light having an infrared wavelength, includes a volume Bragg grating type of input-coupler adapted to receive infrared light having the infrared wavelength and couple the received infrared light into the waveguide. The volume Bragg grating includes a lower boundary and an upper boundary that is closer to the output-coupler than the lower boundary. A k-vector angle of the volume Bragg grating at the lower boundary is greater than a k-vector angle at the upper boundary, with k-vector angles of the volume Bragg grating between the lower and upper boundaries gradually decreasing as distances decrease between grating planes of the volume Bragg grating and the upper boundary. Additionally, the volume Bragg grating preferably has an angular bandwidth that is no greater than 5 degrees.

摘要： 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.
