Abstract: The present invention relates to a spectroscopic analyzing apparatus having a structure for enabling detection of a continuous spectrum over an overall detecting region by sharing the overall detection wavelength range to a plurality of detectors. The spectroscopic analyzing apparatus has a spectroscope, a plurality of detectors, and direction changers provided in connection with one or more detectors among the plurality of detectors. The spectroscope separates incident light into one or more wavelength components. The respective detectors are arranged such that the optical path lengths from the spectroscope to the centers of the photodetecting faces thereof are made coincident with one another. The respective direction changers are arranged on the optical paths of the wavelength components that propagate from the spectroscope to the detectors, and changes the propagation directions of the wavelength components, whereby the direction changers function to adjust the optical path lengths of the wavelength components.

Abstract: A two-beam interferometer for Fourier Transform spectroscopy has a double pivot scanning mechanism. The interferometer has two rigid pendulums that are each rotatable to swing around an associated one of distinct axes of rotation. A linkage links the two rigid pendulums to each other and constrains their rotation relative to each other. The interferometer has bearings, which may be flexure bearings, for rotatably mounting the two pendulums to swing around an associated one of the distinct axes of rotation and a first and a second bearing linking the linkage to an associated one of the pendulums. The two rigid pendulums, the linkage and the bearings can be a monolithic structure.

Abstract: Generating a multispectral or hyperspectral image of an image source with an optical system having an adjustable, wavenumber-dependent point spread function, by collecting panchromatic images of the image source, each of which corresponds to a selected point spread function and includes a measured intensity data set corresponding to a range of wavelengths, transforming the panchromatic images into the spatial frequency domain by using a Fourier transform, solving a matrix equation at each spatial frequency, in which a vector of the transformed panchromatic images is equal to the product of a predetermined matrix of discrete weighting coefficients and a vector representing a wavenumber content of the image source at each spatial frequency, resulting in a determined wavenumber content of the image source in the spatial frequency domain, and inverse transforming the determined wavenumber content of the image source from the spatial frequency domain into the image domain, resulting in the multispectral or hyperspectral image.

Abstract: The static MMS spectral reconstruction process is optimized using algorithmic methods. Because the static MMS encodes spectral information across the detector plane in a highly non-local way, optical errors have a non-local effect on the reconstruction which introduces noise and errors at regions throughout the spectral range. Mathematical signal processing techniques are used to condition and de-convolve the spectral image to compensate for non-ideal system behavior. Spectral signal-to-noise and accuracy are both improved, while the inherent resolution and etendue advantages of the static MMS technique are retained.

Abstract: A dispersive, diffraction grating, NIR spectrometer that automatically calibrates the wavelength scale of the instrument without the need for external wavelength calibration materials is shown. The device shows: 1) a low power He—Ne laser at right angles to the source beam of the spectrometer; 2) a folding mirror to redirect the collimated laser beam so that it is parallel to the source beam; 3) the tendency of diffraction gratings to produce overlapping spectra of higher orders; 4) a “polka dot” beam splitter to redirect the majority of the laser beam toward the reference detector; 5) PbS detectors and 6) a software routine written in Lab VIEW that automatically corrects the wavelength scale of the instrument from the positions of the 632.8 nm laser line in the spectrum.

Abstract: A compact Raman and fluorescence spectroscopy system that uses a microprism or micromirror based optical structure to accomplish the introduction of excitation radiation with compactness and simplified system configuration for portable or mobile spectroscopy applications. A microprism may be glued to a surface location of a focusing lens in the system to directly receive the illumination signal without intervening optical components. Alternatively, the microprism may be simply placed in close physical proximity of the focusing lens without being glued thereto. On the other hand, a micromirror may be used instead of the microprism. The illuminating photons received by the microprism or micromirror may be directly transferred to the sample under investigation via the focusing lens. The compact system may be made portable and may further include an on-board spectrometer with or without a display unit. For chemical detecting applications, a detector (e.g., a CCD array) may also be provided along with the spectrometer.
