Abstract

See full text

A projector can include a projection lens that is positioned substantially one focal length away from a spatial light modulator. The projector may also include a non-imaging optic configured to illuminate the spatial light modulator. The non-imaging optic may include a light emitter and an etendue-preserving reflector. The projector can be configured to project an image created by the spatial light modulator at a distance using light from the non-imaging optic.
