Abstract
A stereo projection optical system includes a polarizing beam splitter, a 2-way wheel, a digital micro-mirror device, and a total internal reflection prism. The polarizing beam splitter is configured for emitting two light outputs. The 2-way wheel includes a reflective region and a transmissive region. The reflective region is configured for reflecting the light outputs and the transmissive region is configured for transmitting the light outputs. The digital micro-mirror device is configured for superimposing spatial information on the light outputs. The total internal reflection prism configured for coupling the light outputs of the 2-way wheel into the digital micro-mirror device and transmitting a light output of the digital micro-mirror device. 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.
