Polarization light modulators are based on an interferometric design in which a polarizing beam splitter serves as a polarizer and analyzer. A polarization displacement device shifts orthogonally polarized light beams parallel to the long axis of their elongated cross sections. Phase shifts are imparted to the orthogonally polarized beams by linear array MEMS optical phase shift devices. The output of the light modulator is a line image which may be scanned to form a two-dimensional image. Features to improve brightness, contrast and overall compactness of design are disclosed.
