摘要： A projection display apparatus (10) uses a modulation optical system (200) that includes a liquid crystal device (210) in combination with a wire grid polarization beamsplitter (240), a wire grid polarization analyzer (270) and a projection lens (285) to form an image. In order to achieve high contrast and maintain high brightness levels, a compensator (260) is provided for minimizing leakage light for pixels in the black (OFF) state.

摘要： A beam splitter for color imaging apparatus is disclosed. The beam splitter comprises two prism elements which are joined together with a dichroic interference filter interposed between the two elements. An input beam to the beam splitter is divided into a first output beam which is reflected from the filter and a second output beam which is transmitted through the filter. In order to provide a beam splitter of a generally triangular cross section in which one of the output beams has the desired spectral content for a luminance channel in the imaging apparatus and the other output beam has the desired spectral content for a chrominance channel, the interference filter is formed of alternate layers of SiO.sub.2 and TiO.sub.2 and is disposed such that an input light beam to the beam splitter has a relatively small angle of incidence on the filter.

摘要： A projection apparatus (10) has an LC modulator panel (60) with photoresponsive layer (316), segmented into a first, second, and third portion, each spatially separated. An image writing section (120) forms a first, second, or third image within the corresponding portion of the LC modulator panel by scanning successive lines of image writing light to energize the photoresponsive layer. The image writing section has at least one grating electromechanical system for modulating a narrow-band light source (70) by providing diffracted and non-diffracted orders and a scanning element (98) for directing a line of light toward the LC modulator panel to energize the photoresponsive layer. An illumination section (130) directs the illumination beams for modulation by the LC modulator panel. Polarizing beamsplitter (24r, 24g, 24b), polarize and direct the illumination beams toward the LC modulator panel and directs modulated light toward projection lens (32).

摘要： A digital cinema projector (100) for projection of color images onto a display surface comprises a light source (116), which produces a beam of light. Beam-shaping optics (130) homogenize and focus the beam of light and color splitting optics (132) separate focus beam of light into separate color beams. A first modulation optics system comprises a prepolarizer (212), which prepolarizes a first color beam; a wire grid polarization beamsplitter (224), which transmits a first predetermined polarization state of the prepolarized beam; a reflective spatial light modulator (204), which alters the transmitted prepolarized beam with information and reflects the image bearing first color beam through the wire grid polarization beamsplitter (224); and a wire grid polarization analyzer (228), which transmits the image bearing first color beam and attenuates unwanted polarization components. A recombination prism (232) combines the first color beam from the first modulation optical system with other image bearing color beams to create a full color image bearing beam. A projection lens system (150) projects the full color image bearing beam onto the display surface (140).

摘要： Disclosed is an optical device comprising a polarizer package comprising an integrated combination of an absorbing layer and a compensator. Two of the identical polarizer packages can be crossed and used in a transmissive optical device. This polarizer package can also be used in combination with a reflective plate and a quarter wave plate in a reflective optical device. Such polarizer packages exhibit an improved viewing angle characteristic across all wavelengths of interest, has a large tolerance for compensators to be aligned relative to their preferred directions, and can be used within an LCD or emissive display system.
