Classification: CPC G | IPC F  G

Claim 0:
1. A system comprising:
optics;
an illumination system comprising:
one or more light sources;
an illumination light combiner to create a color combined illumination pupil from light from the one or more light sources, and to direct the color combined illumination pupil to the optics;

a liquid crystal on silicon display panel (LCOS) to modulate the light from the optics and to direct the modulated light back to the optics, an output pupil of the LCOS matched to the color combined illumination pupil created by the illumination light combiner;
an in-coupler to a combiner waveguide to receive the modulated light from the LCOS, after it passes through the optics;
wherein the color combined illumination pupil from the illumination system is directed through the optics, then to the LCOS for modulation, and back to the optics, such that the color combined illumination pupil directed to the LCOS and the modulated light from the LCOS both pass through a shared subset of the optics.
