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.

摘要： An optical integrating bar (1) is square or rectangular in cross-section (8) having first and second axes (9,10) each perpendicular to opposite sides of the cross-section. Source light beams (14,15) are transmitted to the optical integrating bar in a direction perpendicular to the cross-section. The source light beams exhibit first, second, or first and second polarization states that are orthogonal to each other. The first, second, or first and second polarization states are aligned or substantially aligned with the first, second, or first and second axes of the optical integrating bar, respectively, when the source light beams are transmitted to the optical integrating bar. In this manner, combined light exiting the optical integrating bar maintains or substantially maintains the polarization of each of the source light beams.
