Abstract:
1. An apparatus, comprising: a waveguide including an in-coupling region for receiving input light into the waveguide and an out-coupling region for emitting output light from the waveguide; a plurality of in-coupling mirrors disposed within the in-coupling region of the waveguide and orientated to reflect the input light down the waveguide towards the out-coupling region as guided light, wherein the in-coupling mirrors are laterally offset from one another within the in-coupling region to each reflect a different lateral portion of the input light while not reflecting the different lateral portions of the input light directed to other in-coupling mirrors; and a plurality of out-coupling mirrors disposed within the out-coupling region of the waveguide and orientated to reflect the guided light out of the waveguide as the output light, wherein the out-coupling mirrors each include:
