1. A near-eye display comprising:

  • a waveguide that propagates angularly related beams over a limited first range of angles,an image generator that generates angularly related beams over a second wider range of angles for forming a virtual image,an input aperture of the waveguide including a plurality of controllable components,each of the controllable components of the input aperture being selectively operable as a diffractive optic for injecting a subset of the angularly related beams over a limited portion of the second range of angles for propagating the subset of angularly related beams along the waveguide within the first range of angles,an output aperture of the waveguide including a plurality of controllable components,each of the controllable components of the output aperture being selectively operable as a diffractive optic for ejecting a corresponding subset of the angularly related beams out of the waveguide toward an eyebox, anda controller that synchronizes operation of the controllable components of the output aperture with the propagation of different subsets of angularly related beams along the waveguide for ejecting the subsets of angularly related beams out of the waveguide for presenting the virtual image within the eyebox.
