Abstract:
A method for spatial registration and spectral correction for interferometer based spectral imaging which can be used to obtain spectral images of a moving object, the method comprising the steps of (a) using an interferometer based spectral imager for acquiring spatial and spectral information of the moving object; and (b) correcting the spatial and spectral information for movements of the moving object via a spatial registration and spectral correction procedures for obtaining corrected spatial and spectral information.
Abstract:
A spectral imaging method for detecting and analyzing fluorescent in situ hybridizations (fig. 5) employing numerous chromosome paints (fig. 9) and/or loci specific probes each labeled with a different fluorophore or a combination of fluorophores, the method is highly sensitive both in spatial and spectral resolutions (fig. 6) and is capable of simultaneous detection of dozens of fluorophores or combinations of fluorophores (fig. 7). The method of the present invention can be used for the detection of fluorescently painted complete sets of chromosomes and/or multiple loci from a species such as human (fig. 10).

Spectral imaging methods (fig. 2) for biological research, medical diagnostics and therapy to be used to detect spatial organization and to quantify cellular (fig. 5) and tissue natural constituents, structures, organelles and administered components such as tagging probes (fig. 27) and drugs using light transmission (fig. 9), reflection, scattering and fluorescence emission strategies (fig. 7), with high sensitivity and high spatial and spectral resolutions.
Abstract:
An interference fringe pattern generator forms an interference fringe pattern from the light rays diffused from a region of an object positioned against a background. A planar array of detector pixels is arranged to capture an image of the interference fringe pattern. A storage medium records information indicative of intensity values of the image of the interference fringe pattern captured by a selected group of pixels of the planar array of detector pixels. The information is recorded as a function of the optical path difference values traversed by the diffused light rays through the interference fringe pattern generator for each of the pixels in the selected group of pixels. A processor determines the spectral characteristics of the object based on the information indicative of the intensity values recorded by the storage medium and the optical path difference values traversed by the diffused light rays.
Abstract:
Disclosed are devices (100-2, 100-4) imaging radiation from a scene that includes two materials with spectral characteristics in two different wavelength regions. A lens (9) forms an image of the scene on a part (1a) of detector (1) that includes an array pixels. A blackbody source (60) positioned within the device housing (30) illuminates a separate part (1b) of the detector that does not receive radiation from the scene . The corresponding signal is used to correct the pixel signals produced from the scene radiation.
Abstract:
A system analyzes radiation from a scene in a field of view that includes a gas cloud with absorption characteristics in a wavelength band. The system includes first and second devices. The first device includes a detector and produces pixel signals that include information associated with absorption of radiation in the gas cloud wavelength band. An image of the scene is formed on the detector based on the pixel signals. A non-predetermined region of the scene within the field of view in which the gas cloud is present is identified based on the pixel signals. The second device includes a detector and a lens, and receives the identified region of the scene. The system determines a distance between the identified region of the scene and the system based on the lens focus relative to the identified region of the scene in an image formed on the detector by the lens.

Abstract:
An optical device includes two prisms and a beamsplitter configuration. A first of the prisms has a first surface associated with a source and a second surface oblique to the first surface. A second of the prisms has a first surface associated with a detector and a second surface oblique to the first surface. The second surface of the first prism overlaps with the second surface of the second prism to define an interface region that partially extends along at least one of the second surfaces. The prisms are optically attached at the interface region, and the beamsplitter configuration overlies the interface region. A beam emitted by the source propagates through the prisms along two optical paths and reaches the detector as two coherent beams. Beams that propagate along the two optical paths are reflected from the beamsplitter configuration and transmitted by the beamsplitter configuration exactly once.
