摘要： Apparatus and methods are provided for implementing a full width array material scanning spectrophotometer by integrating a Fabry-Perot cavity filter with a silicon photodetector and a light focusing device (an optical guide or a SELFOC® lens). The material to be scanned is illuminated by a broad band illumination source (white LEDs or a fluorescence light source). The Fabry-Perot cavity gap can be tuned electromechanically to get multiple measurements to resolve the spectral distribution of the transmitted light signal. The array spectrophotometric architecture facilitates an elongated, substantially linear band detection and the associated spectral reconstruction technique resolves spectral distribution in the presence of multiple resonant peaks.

摘要： A spectral filter includes a two-dimensional array of Fabry-Perot cavity structures, a controller, and a sampling circuit used to switch the Fabry-Perot cavity. The filter receives an incoming image, the sampling circuit switches the cavity to generate a filter image, and the filtered image is detected by the photodetectors to convert a filtered image into digital data. The controller coordinates all the image captures functions of the spectral filter.

摘要： A tunable Fabry-Perot filter (8, 118, 218, 318, 418) includes substrates (10, 12) with parallel generally planar facing principal surfaces (14, 16) including spaced apart facing reflective surface regions (20, 22) that are at least partially reflective over a wavelength range and define an optical gap (Gopt) therebetween. At least one substrate of the pair of substrates is light transmissive over the selected wavelength range to enable optical coupling with the optical gap. Electrodes (24, 26) are disposed on the facing principal surfaces of the substrates. The electrodes on the facing principal surfaces of the substrates are define an electrode gap therebetween such that electrical biasing of the electrodes simultaneously modifies the optical and electrode gaps.

摘要： The present disclosure is directed to a system and method to render spatially uniform memory colors when images printed with CMYK primaries are not rendered uniformly due to output device quality errors. The disclosed method uses an array of sensors to scan a test image. Colors of interest are printed at the desired location first and then adjusted (iterated) to achieve a desired output quality. Iterations are carried out on the image on desired memory colors at the spatial resolution available in the measurement system. Colors of pixels are modified based on position where the pixels will be rendered, thereby compensating for any position/process related differences. Also disclosed is a process for incorporating modified memory colors before rendering, and the extension of memory color concepts to adjust colors for the uniform blocks (not edges), with uniformity defined by user definable thresholds.

摘要： A tunable Fabry-Perot filter is supported on a substrate which may be transparent. A transparent support body is supported by the substrate and carries a first reflector. A second reflector is supported on the substrate. The first and second reflectors define a gap therebetween. The size of the gap is adjustable by flexing of the support body to modulate a wavelength of light output by the filter.

摘要： A projection system includes a display apparatus comprising a plurality of tunable Fabry-Perot filters, each of the filters being configured for shifting between a state in which the filter transmits radiation in a bandwidth in the visible range of the electromagnetic spectrum and a state in which the filter transmits radiation in a bandwidth outside the visible range of the electromagnetic spectrum. An illuminator provides light to the plurality of Fabry-Perot filters. A control system receives image data and controls the display apparatus to project an image onto an associated display surface. The control system includes a modulator which provides wavelength modulation signals to the plurality of Fabry-Perot filters to modulate a color of pixels in the image and causes selected ones of the Fabry-Perot filters to shift into the bandwidth outside the visible range to modulate the brightness of pixels in the image.
