Abstract
An image waveguide includes first and second surfaces being non-parallel and opposite to each other. The image waveguide receives input light from an image source along an optical path disposed at least partially between the first and second surfaces. The first reflective surface receives and reflects light from the image source to the second reflective surface. The image waveguide further includes an out-coupling region included in the first reflective surface. The second reflective surface receives and reflects light from the first reflective surface to the out-coupling region to pass light out of the waveguide.
