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 apparatus and method of printing images onto a photosensitive media (140) using multiple reflective spatial light modulators (87, 88, 89, 90, 95, 97). In the apparatus and method, illumination optics uniformize and image light from at least one light source (20) through polarization beamsplitting elements (60, 63). The polarization beamsplitting elements (60, 63) divide the illumination light into two polarization states. One polarization state of the illumination light illuminates the reflective spatial light modulators (87, 88, 89, 90, 95, 97) in a telecentric manner. The reflective spatial light modulators (87, 88, 89, 90, 95, 97) are addressed with image data signals. The reflective spatial light modulators (87, 88, 89, 90, 95, 97) modulate the polarized illumination light on a site by site basis and reflect the modulated light back through the polarization beamsplitting elements. The modulated light beams are combined to form an image, which is directed through a print lens assembly (110) to expose a photosensitive media (140). The position of the spatial light modulators (87, 88, 89, 90, 95, 97) can be changed, and a new image can be printed.

摘要： A method of printing (10) to a photosensitive media contains the step of imaging light from a light source through an optics assembly to a polarization beamsplitter (80). The polarization beamsplitter (80) produces a first polarized state and a second polarized state. The first polarized state is directed to a first filter to a first spatial light modulator. The first spatial light modulator is addressed with a first color signal to modulate the first polarized beam which is reflected back through the polarization beamsplitter (80). A second polarized light is passed through a second filter to a second spatial light modulator. A second color signal causes said second spatial light modulator to reflect a second modulated light beam through the polarization beamsplitter (80). The first and second modulated light beam are focused through print lens (110) onto a photosensitive media.

摘要： A projection apparatus (10) has an illumination section (68) that provides at least a first, a second, and a third component wavelength illumination. At least two component wavelength modulating sections accept and modulate the component wavelength illumination to provide a modulated component wavelength beam. Each component wavelength modulating section has a portion of a monochrome transmissive liquid crystal modulator panel (118) that has been segmented into at least a first, a second, and a third spatially separate portion. A component wavelength polarizer directs substantially polarized light to the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An illumination path Fresnel lens focuses incident illumination from the component wavelength polarizer through the corresponding portion of the monochrome transmissive liquid crystal modulator panel. An analyzer conditions the polarization of the modulated component wavelength beam. A lens forms an image of superimposed component wavelength beams for projection onto a display surface (40).

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 monocentric autostereoscopic optical apparatus (10) for viewing a virtual image, electronically generated and projected on a curved surface. For each left and right image component, a separate optical system comprises an image generation system (701, 70r) and projection system (72), the projection system comprising a spherical diffusive surface (40) and a ball lens (30) to provide wide field of view. A monocentric arrangement of optical components images the ball lens pupil (48) at the viewing pupil (14) and essentially provides a single center of curvature (C) for projection components. Use of such a monocentric arrangement, diffusive surface (40), and ball lens (30) provides an exceptionally wide field of view with large viewing pupil (14).

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).
