ABSTRACT:
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.
