  • Patch correction for light steering projector
    Patent number: 12192684
    Abstract: Example embodiments provide systems and methods for correcting non-uniformities of a light beam generated by a multi-emitter light source. In some embodiments a phase modulator displays patch lenses to correct for the non-uniformities. In some embodiments each region of the phase modulator is illuminated by a beam generated by one emitter of the multi-emitter light source. Such region of the phase modulator may display a patch lens for correcting non-uniformities in the corresponding beam which illuminates the region.
    Type: Grant

  • AR HEADSETS WITH IMPROVED PINHOLE MIRROR ARRAYS
    Publication number: 20220091422
    Abstract: Augmented reality headsets. A plurality of tilted pin-mirrors imbedded between an inner surface and an outer surface of a combiner, where the plurality of tilted pin-mirrors are configured to reflect the guided image light towards the eye box, and wherein the plurality of pin-mirrors include one or more gaps between them wherein the one or more gaps allow the passage of an ambient light through the combiner towards the eye box.
