Abstract: A lens bears a plurality of roll-coated layers to pass, to one eye of a viewer, a first image, in a first band of wavelengths, that is appropriate for 3D viewing of a stereoscopic image.

Abstract: An interference coating between a display and an intended viewing area that selectively absorbs incident optical energy in at least one first wavelength region and selectively transmits incident optical energy in at least one second wavelength region.

Abstract: A processor adjusts a first image generated by a projector and a second image generated by the projector in a first manner if the first and second images together include a stereoscopic image, and in a second manner if the first and second images do not include a stereoscopic image.

Abstract: An apparatus and method that reduces laser speckle by using stimulated Raman scattering in an optical fiber. The fiber core diameter and length are selected to achieve a desired output color. An adjustable despeckler is formed by combining two optical fibers in parallel and adjusting the amount of light in each path.

Abstract: A projection screen for selectively reflecting light from a front projector. The screen includes an etalon coating structure with a first layer of reflective material, a second layer of dielectric material, and a third layer of partially reflective semiconductor material. The projection screen produces a reflection having an asymmetric-shaped response in the visible spectrum.

Abstract: Among other things, light that carries information about cooking is directed in a first direction towards a redirection element and, at the redirection element, the light is redirected to be visible to a person cooking.

Abstract: Selective reflective optical apparatus includes a projection screen. The projection screen has structure constructed and arranged to selectively reflect only incident optical energy of a predetermined number of narrow bands of optical wavelength regions.

Abstract: A bezel-less video display that includes a liquid-crystal display panel, a sheet in front of the liquid-crystal display panel, and an optically transparent material which fills the volume between the display panel and the sheet. The sheet has an antiglare coating which has a gloss level less than 50 gloss units at 60 degrees angle of incidence. The antiglare coating also has a transmissive resolution of at least 10 cycles/mm.

Abstract: Broader spectrum light is enhanced with light of a narrower spectrum.

Abstract: Methods, apparatus and system for controlling ambient light to produce controlled ambient light having predefined optical spectrum characteristics in order to effect a modified color gamut of a reflected image that is reflected from a surface. The reflected image including reflected portions of the controlled ambient light and reflected portions of a projected image directed from an image projector to the surface. The reflected image having a first color gamut in the presence of uncontrolled ambient light. The reflected image having the modified color gamut in the presence of the controlled ambient light.

Abstract: A projection screen that includes a multilayer, multiband, single stack device that selectively reflects light with wavelengths in plurality of narrow wavelength bands, and methods for making the screen. The multilayer, multiband, single stack device may be an etalon device. The multiple layers may be deposited on a diffusing substrate. The projection screen may also include a polarizer that coacts with a projector. The projector polarizes the projected light in the narrow wavelength bands into the same polarity and the screen reflects the light with the same polarization and does not reflect light of another polarization. The polarizer may include substrate with a thin polarizing coating. The screen may include a matte surfaced diffuser.

Abstract: A polarizing layer is positioned between a surface and a window. The polarizing layer has a polarizing axis that is positioned to reduce visibility of the image reflected from the window.

Abstract: A plate has a low birefringence and a retardation layer is characterized by a fast optical axis and a slow optical axis. The retardation layer is positioned with its fast optical axis at a rotation angle selected to reduce an s-polarized component of light passing through the retardation layer at a particular angle of incidence.

Abstract: Methods and apparatus for forming two orthogonally polarized beams of light from an unpolarized beam of light using one of at least two different image modes, the forming includes a color filtering process that is based on the image mode being used, and projecting the two orthogonally polarized beams to form an image on a viewing surface. Methods and apparatus for separating an unpolarized light beam into four beams as a function of wavelength and polarization; selectively modulating the four beams respectively using four light valves; and combining the four modulated beams to generate two orthogonally polarized light beams.
