  • Patent number: 5745869
    Abstract: A method for determining the attitude of a spacecraft (1) by observing stars (2) within a starfield (3). A detector (13), camera electronics (14), and computer (15) located on board the spacecraft (1) are used to generate a set of star match groups by matching pairs of stars observed by the detector (13) with pairs of guide stars from a stored database (18) of guide stars. Match groups having small numbers of stars are eliminated. Non-eliminated match groups are validated. Redundant match groups are eliminated. A match group having the largest number of stars is selected. Finally, the attitude of the spacecraft (1) is derived from positions of guide stars within the selected match group. The guide star database (18) can be broken into an acquisition guide star database (8) and a supplementary guide star database (9). The field of view (20) of detector (13) can be broken into a grid of pixels overlaid by a grid of superpixels (21).

  • Patent number: 5642191
    Abstract: An spectrophotometer system (100) separately images rays of optical radiation in a plurality of wavelength bands from a distant object into a plurality of distinct wavelengths simultaneously and projects the separate images upon a detector (124). Each distinct wavelength is within a corresponding one of the plurality of wavelength bands. The apparatus includes a lens system comprising an objective lens (104), first and second field lenses (108, 116), a collimating lens (118), and a re-imaging lens (120) all disposed coaxially with respect to each other along an optic axis (110). The objective lens (104) and the first field lens (108) coact to cause rays of optical radiation emitted by the object to form an image at a first focal plane. An aperture (112) at the first focal plane passes rays of the optical radiation corresponding to a predetermined portion of the object. The second field lens (116) causes rays from the image at the first focal plane to form an image at a second focal plane.

  • Patent number: 5627639
    Abstract: An imaging spectrometer that includes a mask (214) that has an array of n rows (302) and n columns (304) of transmissive elements (306) for transmitting the light from a plurality of locations of an image and of opaque elements (308) for blocking light from a plurality of locations of the image. The transmissive and opaque elements are arranged in a Hadamard pattern having rows (and columns) that are different cyclic iterations of an m-sequence. A grating (110) disperses the transmitted light from the transmissive elements (306) in a linear spatial relationship in a predetermined relationship to the wavelength of the transmitted light. A detector array (406) has a plurality of detector elements (408) arranged in a row to receive the dispersed transmitted light from the grating (110). Each detector element (408) provides an intensity signal indicative of the intensity of the light impinging thereon.

  • Patent number: 5612786
    Abstract: A method for measuring the contours (30) of a three-dimensional object (4); and a method for calibrating an optical system (2, 8). The object (4) is placed into the field of view of the optical system (2, 8). The optical system (2, 8) is activated to obtain a set of data giving a phase (x.sub.t) at each of a plurality of pixels corresponding to the object (4). The phases (x.sub.t) are unwrapped, e.g., by a method of ordered phase unwrapping. The unwrapped phases are converted into a set of three-dimensional coordinates (x.sub.s, y.sub.s, z.sub.s) of the object (4) for each of the pixels. These coordinates (x.sub.s, y.sub.s, z.sub.s) can be portrayed on a display of a computer (10). The method for calibrating the optical system (2, 8) shares several common steps with the above method. In addition, coordinates of a test calibration fixture (38, 46) are first mechanically measured.

  • Patent number: 5600486
    Abstract: A color separation microlens is fabricated to be a single micro-optical element made up of a color separation grating integrated with a refractive lens. The color separation microlens separates the spectrum into distinct color spots and focuses these spots to a common plane. The spots fall at the locations of the different diffraction orders of the grating. The color separation is done by the grating, and the focusing is done by the lens. The color separation microlens can be fabricated as a monolithically integrated element (an element in which the grating and the lens are combined to a single surface) and can also be fabricated as a dual-sided thin wafer (a wafer in which the grating is on one side and the lens is on the other).

  • Patent number: 5598261
    Abstract: A wavefront sensor for use in a scanning imaging system for generating focused and defocused images of an object scene that is being imaged by the imaging system from a single input optical beam impinged thereon. The two images are combinable using phase diversity techniques for calculating the wavefront aberrations that are present in the imaging system. The wavefront sensor includes a first linear photodetector array for forming a best focused image of an object scene as an incoming optical beam scans across the first linear photodetector array. The wavefront sensor further includes a second photodetector array disposed parallel to the first photodetector array. The second photodetector array is provided with a compensator plate for inducing a known focus error in the image that is formed on the second photodetector array as the input optical scans across the second photodetector array. In one embodiment, the two photodetector arrays are configured as CCD arrays on a single substrate.
