Abstract: A spectroscopy system and method in which the optical path following the interferometer includes a Jacquinot stop having an aperture disposed substantially at its focal point. The Jacquinot stop includes a reflective surface substantially non-orthogonal to the longitudinal axis of the path and facing the source of the IR signal containing an interferogram. The aperture passes an inner portion of the incident IR signal, while the reflective surface reflects an outer portion. The reflected outer portion of the incident IR signal, which contains erroneous spectral information due to inherent flaws in the interferometer optics, is thereby effectively removed from the original incident IR signal ultimately used to irradiate the sample, and yet still be made available for use in monitoring background spectra of the sampling optics.

Abstract: An imaging system and method are presents for use in reconstructing spectral data of an object. The imaging system comprises: an optical unit; a pixel array of a detector; and a data processor for receiving and processing image data indicative of light detected by the pixel array and generating reconstructed spectral data of the object being imaged. The optical unit is configured and operable for applying a predetermined coding to an input light field while creating an optical image thereof on a detection plane defined by the pixel array. Therefore, the image data is a function of the predetermined coding and a spectrum of the object to be determined.

Abstract: An apparatus for measuring a wavelength-dependent optical characteristic of an optical system has a light-pattern generation device which generates a pattern of polychromatic light in an object plane. Together with the optical system, a measuring optical unit images the object plane on a spatially resolving light sensor. A dispersive optical element is arranged in a light path between the optical system and the light sensor in such a way that a plurality of images of the pattern with different wavelengths are generated simultaneously on the light sensor. The evaluation device determines the wavelength-dependent characteristic of the optical system from the plurality of images on the light sensor.

Abstract: The present invention relates to a stand-off optical measuring system based on Raman scattering for detecting and identifying chemical threat substances. The system comprises a spectrometer that comprises a dispersive device (104) in front of a 2-dimensional detector (105), the entrance of the spectrometer being a coded aperture (106-109). The measuring system is designed to be able to quickly adapt to different measuring conditions by the coded aperture being a programmable coded aperture.

Abstract: Systems in a flow cytometer having an interrogation zone and illumination impinging the interrogation zone include: a lens subsystem including a collimating element that collimates light from the interrogation zone, a light dispersion element that disperses collimated light into a light spectrum, and a focusing lens that focuses the light spectrum onto an array of adjacent detection points; a detector array, including semiconductor detector devices, that collectively detects a full spectral range of input light signals, in which each detector device detects a subset spectral range of the full spectral range of light signals; and a user interface that enables a user to create a set of virtual detector channels by grouping detectors in the detector array, such that each virtual detector channel corresponds to a detector group and has a virtual detector channel range including the sum of subset spectral ranges of the detectors in the corresponding detector group.

Abstract: An optical filter for an optical data transmission system, including a substrate; a first and a second reflective structure which are spaced apart from each other such that they form a Fabry-Perot cavity, and at least one optical waveguide formed on or in the substrate, via which light can be coupled into the Fabry-Perot cavity and/or out of the Fabry-Perot cavity. The Fabry-Perot cavity formed by the first and the second reflective structure at least partly is a free-beam cavity, and the waveguide is an integrated waveguide which is formed by one or more layers arranged on the substrate, and the first and the second reflective structure are at least partly arranged in a cutout of the substrate or adjoin the cutout.

Abstract: In one aspect, an apparatus includes a first light source that applies first light having a first wavelength as a center wavelength to an object, a second light source that applies second light having a second wavelength as a center wavelength longer than the first wavelength to the object, an optical filter that includes first and second regions and that transmits third light produced by the first and second light each passed through or reflected by the object, first and second optical detectors that determine first and second amounts, respectively, of the third light passed through the first and second regions. The transmission ranges of spectral transmission curves of the first and second regions are located between the first wavelength and the second wavelength. The spectral transmission curve of the first region has a width at half maximum different from that of the spectral transmission curve of the second region.

Abstract: The present disclosure provides wavelength discriminating imaging systems and methods that spatially separate (over different depths) the wavelength constituents of an image using a dispersive element or lens, such that this spectral information may be exploited and used. The wavelength constituents of an image are deconstructed and identified over different depths using the dispersive element or lens.
