Abstract:
1. A stereo projection optical system, comprising: a first polarizing beam splitter configured for separating a light input into a first polarized light component and a second polarized light component which is substantially orthogonal to the first polarized light component; a first transmission-type spatial light modulator configured for receiving the first polarized light component and converting the first polarized light component into the second polarized light component and emitting the second polarized light component; a second transmission-type spatial light modulator configured for receiving the second polarized light component and converting the second polarized light component into the first polarized light component and emitting the first polarized light component; and a second polarizing beam splitter positioned to receive the light outputs of the first, second spatial light modulators and configured for combining the first, second polarization light components respectively emitted by the first, second spatial light modulator into a single light output.
