| 20090141242 | STEREO PROJECTION APPARATUS USING POLARIZED SOLID STATE LIGHT SOURCES - A digital image projector includes a first polarized light source; a second polarized light source that is orthogonal in polarization state to the first polarized light source; a polarization beamsplitter disposed to direct light of either the first or second polarization along a common illumination axis; a MEMS spatial light modulator; and projection optics for delivering imaging light from the MEMS spatial light modulator. | 06-04-2009 |
| 20100103519 | ETENDUE MAINTAINING POLARIZATION SWITCHING SYSTEM AND RELATED METHODS - Etendue maintaining polarization switching occurs, according to various embodiments, with a mirror that quickly transitions between two positions. Light having uniform polarization is transmitted to the mirror. Light reflected off of the mirror in one of the two positions has its polarization changed, whereas light reflected off of the mirror in the other of the two positions has its polarization maintained. Thereafter, the polarization-changed light and the polarization-maintained light easily may be recombined in an entendue-maintaining manner. Because the recombined light includes two different polarization states, stereoscopic images may be generated. | 04-29-2010 |
