    摘要： Light filter apparatus for receiving a light beam having wavelengths in a selected band and for dispersing the light into a plurality of rays, with each ray having a different wavelength for which the intensity peaks. The peak wavelength varies approximately continuously with displacement of spatial position in a chosen direction along the filter's light-receiving plane. In one embodiment, the filter is a modified etalon structure having at least two reflecting surfaces whose separation distance is not constant but increases or decreases monotonically with distance in a chosen direction in a light-receiving plane of the etalon. Each of these two reflecting surfaces may be planar or non-planar but continuous, or may have a step or staircase configuration. This structure may operate using transmitted light or reflected light. In a second embodiment, an edge filter combination is used to produce a narrow band of transmitted or reflected light having a variable central wavelength that varies with position along the chosen direction. In a third embodiment, a multi-layer thin film structure is used to provide a narrow band of transmitted or reflected light having a variable central wavelength. The filter may be combined with a one-dimensional or two-dimensional array of photosensor elements, which array may be linear, circular or generally curvilinear, one such element receiving a group of adjacent light rays of similar peak wavelength, to provide a plurality of different wavelength readings on an incident light beam for spectrophotometry or colorimetry analysis.

    摘要： A novel structure for a small, inexpensive, and easily replaced infrared source having near blackbody emission over a spectrum of 2-20 micron wavelengths is disclosed. The source element is self-starting and has a life expectancy in excess of 1000 hours at 1700 degrees K, which requires only 22 watts of power to maintain. Because the source is energy efficient, there is no need of auxilliary cooling or added thermal isolation from adjacent components when the source is used in an instrument such as a spectrophotometer.

    摘要： The present is drawn to the use of blocked acid monomers for the incorporation of highly acidic groups, such as strong acids and multiple acids, on the surface of latex particles via emulsion polymerization. In accordance with this, a method of forming latex particulates having high charge density surfaces can comprise the steps of preparing a monomer emulsion including an aqueous phase and an organic monomer phase, wherein the organic monomer phase includes at least one blocked acid monomer; polymerizing the organic monomer phase to form blocked acid latex particulates dispersed in the aqueous phase; and unblocking the blocked acid latex particulates to form acidified latex particulates.

    摘要： A molecular light valve controlled color display. The display is formed through a layer of such molecules between a crossbar array of transparent electrodes, the crossbar intersections forming addressable pixels. A rapid sequencing of primary colors is controlled by molecular light valves congruent with display pixels. Native display resolution for a full gamut of colors is maintained for each pixel via a temporally distributed color pixel scheme. Both still and motion images can be displayed. Molecular valves, or switches, transition between two optically distinct states, e.g., transparent and black.

    摘要： A scan-print device is hand-held and is scanned over the surface of a paper-like rewritable sheet. The sheet has a colorant responsive to a linear array of pixel-sized electric fields written over the sheet by the scan-print device during each scan, producing a bistable pixel (e.g., black or white) in response to field polarity. The bi-stable, rewritable colorant is highly energy efficient, requiring energy only to change an image, not to hold or illuminate it. Once a series of scans sufficient to cover the entire sheet has been made, the printed image appears as if printed conventionally. The print remains stable until reprinted or intentionally erased. Combined with hand-held scanner-copier technology, a portable copier is also implemented.
