Claim 25:
26. A system comprising:
a combiner waveguide to display an image to a user, the combiner waveguide having a near side and a far side;
optics;
an illumination system comprising an illumination prism to direct a-unmodulated light from one or more light sources to the optics, the illumination system positioned on the near side of the combiner waveguide;
a liquid crystal on silicon display panel (LCOS) to receive the unmodulated light from the optics, to modulate the light, and to direct the modulated light back to the optics;
an in-coupler of the combiner waveguide to receive the modulated light from the LCOS, after it passes through the optics;
such that the illumination light to the LCOS and the modulated light from the LCOS both pass through a shared subset of the optics.
