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).

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).

摘要： An autostereoscopic image display apparatus (10) that adapts to sensed feedback data about an observer (12) in order to conform its operation to adapt to the position and intraocular dimensions of the observer. The apparatus (10) uses ball lens projection optics to provide wide field-of-view pupil imaging, providing separate left- and right-eye images to the left and right eye pupils (14l,14r) of the observer (12), respectively. The apparatus (10) compensates for positional variables such as variable interocular distance and variable observer distance from projection optics. At least one observer feedback sensor (52) is disposed to provide feedback data about the observer (12). The feedback data can be used by a control logic processor (50) that, based on the data, adjusts left- and right viewing pupil forming apparatus (36l,36r). The control logic processor (50), based on sensed feedback data, may also vary image content or provide other stimuli such as smell, movement, and sound.

摘要： A head-mounted optical apparatus (10) providing pupil imaging with a very wide field of view. The head-mounted optical apparatus (10) employs a monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated and projected as left and right images from curved surfaces (68). For each right and left image, a ball lens assembly (30) is used to project a displayed intermediate image from the curved display surface (68) toward a beamsplitter (16), which directs an intermediate image toward the front focal surface of a curved mirror (24) that collimates the image to form a virtual image. The beamsplitter (16) transmits the virtual image for each eye to the observer.

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 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： 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).
