Abstract
A display includes a light-guide optical element (LOE) () and a projector arrangement () for injecting an image into the LOE so as to propagate within the LOE by internal reflection at a pair of major faces. The image is coupled out from the LOE by a coupling-out arrangement, exemplified here as internal partially-reflecting surfaces (). The image is coupled out from the LOE in a direction away from the eye of the observer (), and a reflector () reflects the coupled-out image back through the LOE (), towards the eye of the observer (). Reflector () is preferably a selective partial reflector, and may be convex to provide a desired apparent image distance.
