    • A stereo projection optical system includes an image assimilator and a transmission-type light modulator positioned to receive the emergent light of the image assimilator. The image assimilator is configured for superimposing spatial information on the incident light beam and emitting one of a first polarized light component and a second polarized light component. The transmission-type light modulator alternates between a dark state and a bright state. The stereo projection optical systems provide viewers three-dimensional images formed by two alternative polarized lights whose polarizations are perpendicular relative to each other utilizing the transmission-type light modulators.

    • A light source structure of a projector includes at least a solid state lighting element, at least an optical collimator lens, a condenser lens, and a light dispersing apparatus. The solid state lighting element generates a plurality of radial beams, which are incident, to the optical collimator lens. The optical collimator lens converts the radial beams into a plurality of parallel beams which strike the condenser lens. The parallel beams are concentrated and focused by the condenser lens into a projecting beam. The light dispersing apparatus is positioned on at a focal point of the condenser lens and receives the projecting beam to scatter the projecting beam uniformly.
