Original Abstract Submitted

An apparatus includes a first light waveguide including: a first in-coupling diffraction grating to in-couple first input beams of light into the first light waveguide from a first light engine, a first expander to expand the first input beams of light to form first expanded beams of light, a first out-coupling diffraction grating to out-couple the first expanded beams of light; and a second light waveguide including: a second in-coupling diffraction grating to in-couple second input beams of light into the second light waveguide from a second light engine, a second expander to expand the second input beams of light to form second expanded beams of light, and a second out-coupling diffraction grating to out-couple the second expanded beams of light. The first light waveguide provides a first image, and the second light waveguide provides a second image.
