ABSTRACT:
A stereo projection optical system, includes a first polarizing beam splitter configured for separating a light input into a first polarized light component and a second polarized light component; a first transmission-type spatial light modulator configured for receiving the first polarized light component; a second transmission-type spatial light modulator configured for receiving the second polarized light component; a second polarizing beam splitter positioned to receive the light outputs of the first, second spatial light modulators. The first and second transmission-type spatial light modulators respectively generate two images formed by the first polarized light component and the second polarized light component with spatial information. When a viewer wears glasses that have two polarizing lenses whose polarization directions are perpendicular to each other, the viewer can perceive projected images as being three-dimensional.
