    Abstract: This invention is a device, and method for spectral imaging of an object. A plurality of sets of narrow-band light sources (12) such as LEDs are provided. Each set emits illumination radiation in a different narrow spectral band. Each set is activated sequentially to illuminate the object (16). Light reflected from the object or transmitted by the object is focused (26) on a detector array (20) to image the object. Narrower illumination bands are provided by dispersing the emitted light using a dispersive optical element such as a diffraction grating. Alternatively, selected sets or subsets are activated simultaneously with duty cycles that emulate a preselected spectral distribution. For imaging ocular fundus tissue, the illumination light is shaped into an annular beam by an appropriately shaped wave-guide.

    Abstract: A fluorescent in situ hybridization method including the steps of (a) obtaining a chromosome spread of a species; (b) preparing a hybridization composite containing a plurality of chromosomal paints each of the plurality of chromosomal paints being labeled with a different fluorophore-or-combination-of-fluorophores, such that an averaged specific activity of highly repetitive sequences in the hybridization composite substantially equals an averaged specific activity of unique sequences in the hybridization composite; (c) denaturing the hybridization composite and subjecting the hybridization composite to conditions for allowing at least a part of the highly repetitive sequences in the hybridization composite to reanneal while at least a part of the unique sequences in the hybridization composite remaining single stranded; (d) contacting under hybridization conditions the hybridization composite with the chromosome spread; (e) washing away excess of the hybridization composite; and (f) analyzing and presenting images of the now hybridized chromosome spread.

    Abstract: A method and an apparatus for analyzing an optical image of a scene to determine the spectral intensity of each pixel thereof, comprising: collecting and collimating incident light from the scene; passing the light through an interferometer wherein the light is first split into a finite plurality of coherent beams which travel along different optical paths inside the interferometer and then recombine to interfere with each other, the interferometer thereby outputting modulated light corresponding to a predetermined set of linear combinations of the spectral intensity of the light emitted from each pixel; focusing the light outputted from the interferometer on a two dimensional detector array; and processing the output of the detector array to determine the spectral intensity of each pixel thereof; the interferometer being of the translating type in which the optical path difference is varied to modulate the light by translating an element of the interferometer, such that at each instant each detector sees a different point of the scene and its signal is a linear combination of the spectral content of the light coming from each pixel, and that when the scanner completes one interferometer scan, the scene will have been scanned at all relevant linear combinations of the spectral content.
