摘要： A projection apparatus (10) has an illumination section with a light source (20) providing a substantially unpolarized illumination beam of multiple wavelengths. A multiple wavelength polarizer polarizes the substantially unpolarized illumination beam to provide a substantially polarized illumination beam of multiple wavelengths. A uniformizer conditions the substantially polarized illumination beam of multiple wavelengths to provide a uniformized polarized beam of multiple wavelengths. A color scrolling element provides a repeating, scrolled sequence of colors from a set of colors, thereby providing first, second, and third component wavelength illumination. A component wavelength modulating section accepts the sequence of first, second, and third component wavelength illumination from the color scrolling element and sequentially modulates the first, second, and third component wavelength illumination at a transmissive liquid crystal modulator panel (118) to provide a modulated component wavelength beam to a lens for projection toward a display surface (40).

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： 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 projection apparatus (10) for projection of a multicolor image includes a magnifying relay lens assembly (28) as part of the light modulation assembly (38) for each component color. The relay lens assembly (28) increases the effective f/# of incident light to the V-plate assembly (25) or V-prism assembly (27) that serves as dichroic combiner, used to combine modulated light of each color from each light modulation assembly (38) in order to form the multicolor image. The magnifying relay lens assembly (28) also provides a reduced working distance for the projection lens (32), allowing a lower-cost design and facilitating substitution of the projection lens (32) best suited for a display surface (40).

摘要： A printer for printing on a light sensitive media (100) includes a light source (10) and optics. Cross array components and array direction components reduce divergence of the beam from the light. The illumination optics flood illuminates a grating modulator with reduced light beams. Modulator sites on the grating modulator array, are individual addressed which imparts a phase change to the reduced light beams. An imaging lens (70) directs light from the grating modulator array onto the light sensitive media (100). The imaging lens (70) includes a first lens element which converts the light into diffracted and undiffracted light; a spatial filter (80) which discriminates between the diffracted and the undiffracted light; and a second lens element which reconstructs an image of the modulator sites.

摘要： An autostereoscopic optical apparatus (10) provides a stereoscopic virtual image to be viewed by an observer at a left viewing pupil (14l) and a right viewing pupil (14r). Apparatus (10) has left and right image generation systems (100l) for forming left and right curved images, each image generation system having a curved mirror (92), a beamsplitter (102) disposed between the vertex of the curved mirror (92) and the mirror's center of curvature, and an image source (94) for providing image-bearing light to the curved mirror (92). The curved mirror (92) cooperates with the beamsplitter to form an intermediate image of the image source (94). A field lens (112) is disposed near the intermediate image for imaging the mirror center of curvature toward the image center of curvature. A ball lens segment (130) is centered at the image center of curvature for forming the curved image from the intermediate image. A ball lens imaging spherical mirror (24) cooperates with a beamsplitter (16) to form images of left and right ball lens segments (130l, 30r) at left and right viewing pupils (14l, 14r).
