ETENDUE MAINTAINING POLARIZATION SWITCHING SYSTEM AND RELATED METHODS

摘要

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 etendue maintaining manner. Because the recombined light includes two different polarization states, stereoscopic images may be generated.
