1. An image projector comprising:
an illumination module comprising at least one spatially coherent light source;
a phase image generator comprising an array of optical phase shifting elements;
an electronic image controller in electrical communication with the phase image generator; and
a waveguide interposed between the illumination module and an observer and comprising at least two embedded partial reflectors;
wherein the phase image generator is interposed between the illumination module and the waveguide, or between the waveguide and the observer, and the phase image generator includes phase shifts for correcting optical aberrations.
