Abstract
A display system includes an angle-mapped display engine operable to launch angle-mapped image-bearing rays through an image-guiding substrate for display.
Claims12
A display comprising:
- an angle-mapped display engine operable to produce angle-mapped rays corresponding to a visible image without the use of an ocular lens;
- and
- an image-guiding substrate aligned to receive angle-mapped rays directly from the angle-mapped display engine and configured to launch rays corresponding to the visible image, wherein the image guiding substrate further comprises:
- an input optical element configured to receive the angle-mapped rays;
- a substrate configured to propagate angle-mapped rays from the input optical element at a proximal end to a distal end;
- and
- an output optical element configured to receive the propagated angle-mapped rays and launch the propagated angle-mapped rays into a viewing region, wherein at least one of the input optical element and the output optical element includes one or more holographic optical elements.
