Abstract: A method for dynamically registering multiple patterned layers on a substrate (3) comprises: depositing a first layer on the substrate; printing a first pattern (20) on the first layer; depositing a second layer on the first pattern; and printing a second pattern on the second layer while dynamically detecting the first pattern to align the second pattern with the first pattern.

Abstract: 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.

Abstract: An autostereoscopic optical apparatus (10) for viewing a stereoscopic image comprising a left image to be viewed by an observer (12) at a left viewing pupil (14l) and a right image to be viewed by the observer at a right viewing pupil (14r). A left image generation system (70l) forms a left curved intermediate image near the focal surface (22) of a curved mirror (24). A right image generation system (70r) forms a right intermediate image near the focal surface of the curved mirror. A center of curvature of the curved mirror is placed substantially optically midway between the exit pupil and the left optical system (110l) the exit pupil of the right optical system (110r). A beamsplitter is disposed between the focal surface and the center of curvature of the curved mirror.

Abstract: 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.

Abstract: A projection apparatus has an illumination section that provides first, second, and third light sources for providing first, second, and third illumination beams. First, second, and third component wavelength modulating sections modulate the corresponding illumination to provide first, second, or third modulated component wavelength beams respectively.

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.

Abstract: An improved autostereoscopic display apparatus (10) forms left and right virtual images for pupil imaging by forming, through a beamsplitter (16), a real intermediate image near the focal surface of a curved mirror (24). A circular polarizer (90) is disposed at a position between viewing pupils (14l, 14r) and the beamsplitter (16), minimizing glare due to stray light reflection from the curved mirror surface.

Abstract: A light separator splits polychromatic light into longer and shorter wavelength spectral bands. The light separator is defined between opposing side surfaces that are reflective to incident light and further has an input side for accepting the polychromatic light and an output side for providing the separated spectral bands. A first light guiding channel narrows as it extends from the input to the output side and lies between a first dichroic surface for reflecting longer wavelengths and transmitting shorter wavelengths and a first outer surface reflective to incident light. A second light guiding channel narrows as it extends from the input to the output side and lies between a second dichroic surface for reflecting shorter wavelengths and transmitting longer wavelengths and a second outer surface reflective to incident light. A portion of the light separator is common to both first and second light guiding channels.

Abstract: A display apparatus (10) comprises a light source (20) for forming a beam of light. Illumination optics shapes and directs the beam of light. A splitter for splits the beam of light into at least three color beams of light. A modulation optical system (120) for each of the three color beams of light comprises a pre-polarizer (160), a wire grid beamsplitter (170), a reflective spatial light modulator (30), and a polarization analyzer (165). An imaging relay lens (130) in each color provides an intermediate image of the reflective spatial light modulator from the modulated light for that color. A dichroic combiner (26) recombines the modulated light for each given color, such that the multiple color beams form the respective intermediate images along a common optical axis to form a combined intermediate image. A projection lens (32) images the combined intermediate image to a display screen. An imager field lens (140) provides nominally telecentric light to the spatial light modulators.

Abstract: 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.

Abstract: A digital projection apparatus (10) for projection of a multicolor image uniformizes polychromatic light from a light source (12) and provides magnification to the uniformized illumination beam using a base condenser relay (80), providing a reduced numerical aperture for conditioning at a dichroic separator (27). For each monochromatic component color provided from the dichroic separator (27), a reducing relay (82) then demagnifies the illumination beam to provide source illumination to a spatial light modulator (30) at an increased numerical aperture. As a result, color shading across the field is minimized and brightness is optimized.

Abstract: 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 dichroic combiner (26) 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).

As a result, the projection lens (32) has reduced working distance, color shading across the field is minimized, and brightness is optimized.
