Abstract:
A color combining apparatus has first, second, and third color channels, each color channel having a light source that is energizable to direct light of a corresponding first, second, or third wavelength band, respectively, toward a color combining element. The color combining element is a single piece of a solid, transparent material having at least first and second flat coated surfaces that are noncontiguous. The first coated surface is treated to reflect incident light of the first wavelength band onto an optical axis and to transmit incident light of the second and third wavelength bands. The second coated surface is treated to reflect incident light of the second wavelength band and to transmit incident light of the third wavelength band.
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:
An autostereoscopic optical apparatus (10) for viewing a stereoscopic virtual image comprises 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). The apparatus comprises a left pupil imaging system for forming the left image. A right pupil imaging system forms the right image.
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. 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).
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. A lens forms an image of superimposed component wavelength beams for projection onto a display surface (40).
Abstract:
An apparatus for displaying a stereoscopic virtual image to a first viewer (12a) and to a second viewer (12b), where the stereoscopic virtual image is imaged to each viewer at a left viewing pupil (14l) and a right viewing pupil (14r). Configurations using multiple beamsplitters (16) and one or two curved mirrors (24) direct the optical path to first and second viewers (12a and 12b).
Abstract:
An apparatus for providing a light beam has a solid-state laser to emit a polarized input laser light beam that has a first aspect ratio of etendue R 1 . First and second cylindrical lenses collimate the light along orthogonal directions. An edge of a bisecting reflective surface splits the laser light beam into a first portion directed along a first beam path and a second portion along a second beam path, wherein the first and second beam paths each contain emitted light from the solid-state laser. One or more folding reflective surfaces are disposed along the first or second or both beam paths. A polarization rotator rotates polarization of the light along the second beam path. A polarization combiner combines light from the first and second beam paths to form an output beam, wherein the output beam has a second aspect ratio of etendue R 2 not equal to R 1 .

Abstract:
An apparatus (10) for stereoscopic viewing has a first optical channel with a first display (12l) and a first viewing lens assembly (22l), which produces producing a virtual image. At least one optical component of the first viewing lens assembly is truncated (26l) along a first side. A second optical channel has a second display (12r) and a second viewing lens assembly (22r), which produce a virtual image. At least one optical component of the second viewing lens assembly is truncated (26r) along a second side. A reflective folding surface is disposed between the second display and second viewing lens assembly to fold a substantial portion of the light within the second optical channel. The first side of the first viewing assembly is disposed adjacent the second side of the second viewing lens assembly.
