    Abstract: The invention provides an imaging spectrometer that provides a wide field-of-view camera and spectrometer for spectral imaging of a large two-dimensional area of the Earth's surface from an orbiting satellite or airplane. The wide field-of-view camera fore-optics includes spherical optical elements arranged monocentrically. The spectrometer includes an all-reflective coupling design that transfers the curved optical image to one or more compact imaging spectrometers. The spectrometers preferably comprise a spherical convex holographic grating and associated reflective optics for dispersing a collimated optical beam into its spectral components and focusing the spectral image onto a planar detector array. The instrument described herein is designed to operate in a "pushbroom" fashion, that is, the forward motion of the satellite or airplane generates the spatial dimension of the resulting image. Because of its compact optical design and because no additional scanning equipment is required to scan the Earth's surface, the instrument is very compact and light-weight.

    Abstract: A method and system for calibrating color filters employed in polychromatic imaging of a subject includes a scanning mirror (28), telescope (30), filters (104), and a detector array (60) employed for both imaging and calibration processes. A bundle (44) of optical fibers is employed for producing a slit-shaped beam of solar rays which are collimated and applied to a diffraction grating plate (54) or prism (72) to produce a set of dispersed solar rays. The dispersion is based on color. In one position of the scanning mirror, rays from a subject (12) to provide an image are directed through the telescope and scanned across the filters (104) and detectors (102). In another position of the scanning mirror, the set of dispersed solar rays is scanned past the filters and the detectors. Imaging data outputted by the detectors is collected for producing an image (112) of the subject. Data of the dispersed rays is collected for calibrating the color filters. A stored reference color profile (92) of each filter is correlated with the calibration data ( 90) to obtain a set of correction terms which are employed for altering the image data to compensate for any drift in the color characteristics of the filters. A broad band detector detects Fraunhofer spectral lines to serve as a reference standard wavelength for alignment of the system.

    Abstract: In a color measuring instrument, an integrating sphere is used to illuminate the sample and fiber optics are used to carry light diffusely reflected from the sample and from an interior wall of the sphere to a spectrometer. The transmitting ends of the fiber optic bundles are fixed in the housing of the spectrometer as entrance slits for the spectrometer, which includes a fixed grating and one or two arrays of photodetectors to detect the spectra dispersed by the grating from light received from the two transmitting ends.
