ABSTRACT:
Light guides of various shapes are configured to adjust the angle of the individual light rays in a bundle of light within the light guide so that the angle of the respective rays are adjusted towards an acceptance angle of a hologram embedded within the light guide. The hologram embedded in the light guide is configured to eject individual rays towards the display elements when the respective rays are within a range of acceptance angles.
