17. A method, comprising:
projecting, from a plurality of projection points of a light engine, light beams; and
redirecting, using a reflective holographic combiner comprising a plurality of point-to-point holograms, the light beams received from the plurality of projection points to a plurality of eye box points,
wherein the light beams from each projection point are projected to two or more of the plurality of holograms of the reflective holographic combiner, and
wherein the light beams redirected by the two or more holograms illuminate two or more respective eye box points,
wherein neighboring eye box points are illuminated by different ones of the plurality of holograms, and
wherein the plurality of eye box points includes foveal and peripheral eye box points, and wherein the plurality of projection points includes:
two or more foveal projectors that project wide diameter light beams over a small field of view, wherein foveal light beams are redirected to illuminate the foveal eye box points, and
two or more peripheral projectors that project narrow diameter light beams over a wide field of view, wherein peripheral light beams are redirected to illuminate the peripheral eye box points.
