摘要： A system for creating a patterned polarization compensator (550) has a retardance characterization system (560) for optically scanning the spatially variant retardance of a spatial light modulator (210). A compensator patterning system (565) writes a spatially variant photo-alignment pattern on a substrate (555) of a polarization compensator. The patterned polarization compensator is completed by a process that includes providing a photo-alignment layer onto which spatially variant photo-alignment layer is formed, providing a liquid crystal polymer layer onto the photo-alignment layer, and then fixing the liquid crystal polymer layer to form a spatially variant retardance pattern into the structure of the patterned polarization compensator.

摘要： A modulation optical system (40) provides modulation of an incident light beam. A wire grid polarization beamsplitter (240) receives the beam of light (130) and transmits a beam of light having a first polarization, and reflects a beam of light having a second polarization orthogonal to the first polarization. Sub-wavelength wires (250) on the wire grid polarization beamsplitter face a reflective spatial light modulator. The reflective spatial light modulator receives the polarized beam of light and selectively modulates the polarized beam of light to encode data thereon. The reflective spatial light modulator reflects back both the modulated light and the unmodulated light to the wire grid polarization beamsplitter. The wire grid polarization beamsplitter separates the modulated light from the unmodulated light. A compensator (260) is located between the wire grid polarization beamsplitter and the reflective spatial light modulator (210). The compensator conditions the polarization states of the oblique and skew rays of the modulated beam and includes a spatially variant retardance that corrects for a spatially variant retardance of the reflective spatial light modulator.

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).
