Abstract: An apparatus for a near eye display includes an optical waveguide coupler adapted to be optically coupled to one or more light sources, a first prism optically coupled to the optical waveguide coupler, a second prism coupled to the first prism where the first prism faces a first side of the second prism, a spatial light modulator (SLM) optically coupled to the second prism where the SLM faces a second side of the second prism, and focusing optics optically coupled to the second prism where the focusing optics face a third side of the second prism.

Abstract: A system includes a color filter including a first segment configured to transmit first light having a first color and to reflect second light having a second color and a second segment configured to transmit the second light having the second color and to reflect the first light having the first color. The system also includes an integrator rod optically coupled to the color filter, a reflective surface having an aperture on an end of the integrator rod.

Abstract: A system having a color filter having first and second segments. The first and second segments allow respective first and second wavelengths to pass through to a spatial light modulator. The first and second segments also reflect second and first wavelengths, respectively. The reflected first and second wavelengths are recycled and directed towards the color filter.
