Patent Images

1. A near-eye optical display system configured to show images within a field of view (FOV), comprising:

  • a waveguide display comprising one or more diffractive optical elements (DOEs) including an in-coupling DOE configured for in-coupling image light to the waveguide display; and

    a light engine comprising a micro-display, illumination optics, and image optics, in which the micro-display projects the image light into the waveguide display at the in-coupling DOE,wherein the illumination optics includean illumination light source, comprising one of laser or LED (light emitting diode), anda MEMS (micro-electro mechanical system) scanner configured for raster scanning light from the illumination light source to illuminate the micro-display.
