Abstract: A method of making a louver device for a light guide screen. More specifically, in a specific embodiment, a transparent layer is provided. A plurality of similarly angled surfaces are established within the transparent layer. The angled surfaces are coated with a light-reflective material such that the coated surfaces define a plurality of light paths through the transparent layer.

Abstract: A method is provided for recording visible marks on a recording medium using an input beam generated by an electromagnetic radiation source. The method comprises (a) substantially collimating the input beam to provide a substantially collimated beam, and (b) applying the substantially collimated beam to the recording medium to provide the visible mark on the recording medium.

Abstract: A method of displaying an image with a display system includes receiving image data for the image. The method includes generating a first single-color sub-frame and a second single-color sub-frame corresponding to the image data. The method includes projecting the first sub-frame with a first projector onto a target surface. The method includes projecting the second sub-frame with a second projector onto the target surface, wherein the first and the second sub-frames at least partially overlap on the target surface.

Abstract: Provided is a fiber optic rear projection display. In a particular embodiment, provided is a plurality of aligned magnifying layers providing a viewing surface. Each magnifying layer includes a plurality of optical fibers. Each fiber has an input end, a midsection and a magnifying output end. The plurality of input ends are aligned. The plurality of magnifying output ends are aligned in substantially contiguous parallel contact. Equal magnification horizontally and vertically can be realized with inclusion of spacers between the layers of the magnifying output ends that are in substantially contiguous parallel contact.

Abstract: Provided is a black matrix light guide screen display. In a particular embodiment, provided are a plurality of aligned light guides, each having an input end, a midsection and a magnifying output end. A black matrix material is disposed adjacent to the light guides proximate to the magnifying output ends. The plurality of aligned light guides are arranged into a plurality of light guide layers, each layer one light guide thick. The magnifying output ends of each layer are aligned in substantially contiguous parallel contact with interposed black spacers to provide substantially the same magnification vertically and horizontally.

Abstract: A light guide screen louver device. In a particular embodiment, the device includes a translucent layer of material having an inner surface and, parallel thereto, an outer surface. A plurality of reflective louver members are disposed within the layer of material. The louver members are aligned to receive light entering the inner surface from the light guide screen at a low angle relative to the inner surface and direct the light out the outer surface at a high angle relative to the outer surface. In at least one embodiment, the louver members are holographic.

Abstract: Aspects of the disclosure relate to optical scanner apparatuses, hard imaging devices, optical scanning methods, and hard imaging scanning methods. In one aspect, an optical scanner apparatus is described. The optical scanner apparatus may include an optical scanning device configured to reflect a received light beam towards a photoconductor, and a beam direction system optically coupled to the optical scanning device. The beam direction system may include a plurality of reflectors, and each reflector may be configured to transmit light of one polarization while reflecting light of another polarization. The reflectors may be individually configured to permit passage of the input light beam and a light beam reflected by the scanning device and to reflect another light beam reflected by the scanning device.

Abstract: A display apparatus comprising a plurality of light guides and method for producing such an apparatus is disclosed. The display apparatus comprises a plurality of substantially totally internally reflecting (TIR) light guides fashioned to expand a small original optical representation from an input of each light guide to a larger optical representation output at an output of each light guide. Each of the plurality of substantially totally internally reflecting light guides is separated from other substantially totally internally reflecting light guides by a material having a lower refraction index than the core material.

Abstract: An optical projection system that combines a lenslet array and lightvalve with an active color filter. The active color filter may be placed at either the illuminating aperture plane or at any position conjugate or incident to the output plane of the projection lens of the system.
