Light guide combiner with increased field of view (FOV) and eyebox efficiency for enhanced reality applications
Abstract:
A device includes an array of light emitters configured to generate multiple light beams to form an image, the image having a field of view and a planar waveguide having an edge configured to receive multiple light beams from the array of light emitters, each light beam associated with a portion of the field of view. The device also includes a lens array comprising multiple lenses linearly extended to overlap an edge portion of the planar waveguide, the lenses optically coupling the light beams into the planar waveguide, and one or more output couplers in the planar waveguide configured to direct the light beams into an eyebox, wherein the eyebox forms an area that includes a pupil of a viewer of the image.
