Abstract:
A method of analyzing an optical image of a scene to determine the spectral intensity of each pixel of the scene, which includes collecting incident light from the scene; (b) passing the light through an interferometer which outputs 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 detector array; and processing the output of the detector array to determine the spectral intensity of each pixel thereof. If the interferometer is of the moving type scanning in one dimension is required where the detector array is one dimensional, and no scanning when the detector array is two-dimensional. If the interferometer is of the non-moving type scanning is required in one dimension when the detector array is two-dimensional, and in two dimensions when the detector array is one-dimensional.

Abstract:
A spectral imaging method for simultaneous detection of multiple fluorophores aimed at detecting and analyzing fluorescent in situ hybridizations employing numerous chromosome paints and/or loci specific probes each labeled with a different fluorophore or a combination of fluorophores for color karyotyping, and at multicolor chromosome banding, wherein each chromosome acquires a specifying banding pattern, which pattern is established using groups of chromosome fragments labeled with various fluorophore or combinations of fluorophores.
Abstract:
A method of determining the thickness map of a film (14) overlying a substrate (14). This method includes illuminating (10) the film simultaneously from different angles and analyzing spectral intensity of the radiation reflected by each point on the film (14). The analysis is effected by collecting reflected radiation from the film (14), passing the radiation through an interferometer (16) which outputs modulated radiation corresponding to a predetermined set of linear combinations of the spectral intensity of the radiation emitted from each pixel, simultaneously and separately scanning optical path differences generated in the interferometer (16) for each pixel, focusing the radiation outputted from the interferometer (16) on a detector array, and processing the output of the detector array to determine the spectral intensity of each pixel thereof to obtain a spectral intensity distribution. Finally, the method includes further processing the spectral intensity distribution to determine the spatial distribution of the thickness of the film (16).
