摘要： A stereo projection optical system includes an image engine configured for providing light superimposed spatial information, a color selector positioned to receive a light output of the image engine, a transmission-type light modulator positioned to receive an emergent light of the color selector. The color selector is configured for selectively modifying the polarization of the light output according to the wavelength of the light output.

摘要： 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.
