Wide field-of-view projector
Abstract:
This document describes various techniques for implementing a wide field-of-view projector. A wide field-of-view projector may include a spatial light modulator configured to inject light rays into an input wedge. The input wedge acts to output the light rays with an increased fan-out angle. In an embodiment, the spatial light modulator is controlled to inject light rays into the input wedge effective to project an image from the surface of an output wedge that is positioned proximate, and receives light rays with an increased fan-out angle from, the input wedge.
