In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.

Abstract: Beamformers are formed (e.g., carved) from a stack of transparent sheets. A rear face of each sheet has a reflective coating. The reflectivities of the coatings vary monotonically with sheet position within the stack. The sheets are tilted relative to the intended direction of an input beam and then bonded to form the stack. The carving can include dicing the stack to yield stacklets, and polishing the stacklets to form beamformers. Each beamformer is thus a stack of beamsplitters, including a front beamsplitter in the form of a triangular or trapezoidal prism, and one or more beamsplitters in the form of rhomboid prisms. In use, a beamformer forms an output beam from an input beam. More specifically, the beamformer splits an input beam into plural output beam components that collectively constitute an output beam that differs in cross section from the input beam.

Alternatively, the visualization application may be a motion based game or a photography application that displays separate graphics using the vision based pose and the sensor based pose.
