  • Patent number: 11022799
    Abstract: A near-eye display (NED) includes an image replicator and an image combiner. The image replicator is configured for receiving a beam of image light from a source such as an image projector, and splitting the beam into a plurality of second beams of image light. The combiner is configured to relay the plurality of second beams to an eyebox of the NED such that the second beams at the eyebox are laterally offset from one another. The etendue of the NED may be increased by replicating and relaying the image beams.

  • Patent number: 10996476
    Abstract: An optical device with reduced see-through diffraction artifacts for Augmented Reality (AR) applications is provided. The device includes a projector configured to generate an image light and a waveguide optically coupled with the projector and configured to guide the image light to an eye-box. The waveguide includes an in-coupling element configured to couple the image light into the waveguide, and an out-coupling element configured to decouple the image light out of the waveguide. The waveguide includes at least one switchable grating configured to: during a virtual-world subframe of a display frame, decouple the image light out of the waveguide via diffraction, and during a real-world subframe of the display frame, transmit a light from a real-world environment to the eye-box with a diffraction efficiency less than a predetermined threshold.
