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

摘要： A display apparatus (10) including a light source (15) for forming a beam of light (130). A pre-polarizer (45) polarizes the beam of light (130) to provide a polarized beam of light. A wire grid polarization beamsplitter (50) receives the polarized beam of light and transmits the polarized beam of light which has a first polarization, and reflects the polarized beam of light which has a second polarization. A reflective spatial light modulator (55) selectively modulates the polarized beam of light that has a first polarization to encode image data thereon in order to form a modulated beam (360) and reflects the modulated beam back to the wire grid polarization beamsplitter (50). A compensator (260) is located between the wire grid polarization beamsplitter (50) and the reflective spatial light modulator (55) for conditioning oblique and skew rays of the modulated beam (360). The wire grid polarization beamsplitter (50) reflects the compensated modulated beam (360) and the wire gird polarization beamsplitter (50) is rotated in plane to optimize the contrast. A polarization analyzer (60) removes residual light of the opposite polarization state from the compensated modulated beam (360). Image-forming optics (20) form an image from the compensated modulated beam (360).
