ABSTRACT:
A stereo projection optical system includes a polarization converter, a 2-way wheel, a retarder, and an image engine. The polarization converter is configured for converting an incident light into a polarized light which have single polarization. The 2-way wheel includes a reflective region and a transmissive region. The reflective region is configured for reflecting the polarized light and the transmissive region is configured for transmitting the polarized light. The retarder is positioned to receive an emergent light from one of the reflective region and the transmissive region. The image engine is positioned to receive light output of the 2-way wheel and the retarder and configured for emitting the light output comprising spatial information. The stereo projection optical systems provide viewers three-dimensional images formed by two alternative polarized light beams whose polarizations are perpendicular to each other utilizing the 2-way wheel.
