Abstract
An image waveguide includes an in-coupling region for receiving input light into the image waveguide and an out-coupling region for emitting output light from the image waveguide. The in-coupling region includes at least one in-coupling structure orientated to direct the input light into the waveguide for propagation towards the out-coupling region as guided light. The out-coupling region includes a two dimensional array of out-coupling mirror structures orientated to reflect the guided light out of the waveguide as the output light.
