Abstract: A spectroscope is provided with a point light source which emits a dispersed light having a plurality of wavelengths, a first optical system which collimates the dispersed light which is emitted from the point light source into an approximate parallel light flux, a dispersing element which disperses the approximate parallel light flux, and a second optical system for condensing the dispersed light flux near a focal plane. Aberrations for a plurality of wavelengths of an off-axial light flux are compensated in the second optical system. By doing this, it is possible to provide a spectroscope which has a high wavelength resolution.

Abstract: The invention is a method and apparatus for determining characteristics of a sample. The system and method provide for detecting a monitor beam reflected off a mirror, where the monitor beam corresponds to the intensity of light incident upon the sample. The system and method also provide for detecting a measurement beam, where the measurement beam has been reflected off the sample being characterized. Both the monitor beam and the measurement beam are transmitted through the same transmission path, and detected by the same detector. Thus, potential sources of variations between the monitor beam and the measurement beam which are not due to the characteristics of the sample are minimized. Reflectivity information for the sample can be determined by comparing data corresponding to the measurement beam relative to data corresponding the monitor beam.

Abstract: A field multiplexed dispersive imaging spectrometer (20). The novel system includes foreoptics (22) for receiving incoming electromagnetic energy, a disperser (24) disposed to receive energy from the foreoptics (22), and a focal plane array (28) disposed to receive energy from the disperser (24). The disperser (24) is a computer generated holographic disperser designed to disperse light into several, overlapping diffraction orders. In the preferred embodiment, the disperser (24) is designed with greater energy in the central, undiffracted order than in the other diffracted orders. The system (20) also includes a processor (30) which takes the data detected by the focal plane array (28) and generates a representation of the input image in several color bands using an iterative restoration algorithm (32).

Abstract: In a spectrophotometer, the following formula is stored in advance as a correction formula of a rotation angle in a correction formula storing portion; nullnullnullnullnullAnullsin (C1nullnullnullnulla)nullBnullsin (C2nullnullnullnullb)nullnullc, wherein C1, C2 represent coefficients theoretically determined in advance by a structure of a reduction mechanism, and A, B, nulla, nullb, nullc are coefficients specific to the reduction device which are calculated based on measurement results of a plurality of bright line spectrums through fittings by a coefficient determining portion. In case a sample is measured actually, when a desired wavelength is set, a rotation angle correcting portion corrects a rotation angle null corresponding to the desired wavelength to calculate nullnull by applying the above-stated correction formula, and then, controls a motor so that a diffraction grid is rotated by the angle nullnull.

Abstract: The hyperspectral imager includes a diffraction grating, a collecting reflecting element and a reimaging system. The diffraction grating has an entrance slit formed at an entrance slit location therein. The entrance slit has a long dimension oriented in a y-direction. The entrance slit transmits the radiation from a slice of an incoming scene image. The collecting reflecting element receives the transmitted radiation of the incoming scene image and reflects the transmitted radiation to a diffractive surface of the diffraction grating. Grooves on the diffractive surface are substantially parallel to the y-direction. The reimaging system receives radiation diffracted by the diffractive surface. The reimaging system produces a spectral image of the entrance slit at a focal surface. The spectral image provides a spectrum of radiation propagating through the entrance slit into the hyperspectral imager such that the spectrum of radiation from a first region in the y-direction can be distinguished from the spectra of radiation from other regions in the y-direction.

Abstract: Spectroscopy apparatus for spectrochemical analysis of a sample having an excitation source (60) for providing spectral light (62) of the sample for analysis. The spectral light (62) is analysed via an optical system (66-66-68) that includes a polychromator (70, 74-80) and solid state multielement array detector (82). The elements (i.e. pixels) of the detector (82) are serially read by means (84) to provide light intensity measurements as a function of wavelength. A problem is that the elements (pixels) of the detector (82) continue to accumulate charge during the serial read-out. This is avoided by providing an optical shutter (72) for blocking the spectral light (62) whilst elements (pixels) of the detector (82) are being serially read. Shutter (72) has a piezoelectric actuator which is preferably a bimorph mounted as a cantilever. It is preferably located adjacent to the entrance aperture (70) of the polychromator. Bimorph structures for the actuator and drive and protective circuit arrangements are also disclosed.

The present invention is characterized by improvements made to a spectrometer for spectrally dividing the light under measurement by transmitting the components thereof at different, wavelength-by-wavelength angles, and receiving and detecting the light under measurement thus spectrally divided by the chromatic dispersion device using an optical detector. The apparatus according to the present invention comprises a refractive index compensation means for compensating changes in the angle at which the chromatic dispersion device transmits the light under measurement, according to changes in the refractive index of the medium in which the chromatic dispersion device is placed.

Abstract: An optical spectrometer comprises at least two coupling apertures with different mode field diameters, a means for dispersing the light beams exiting each of the coupling apertures along a dispersion axis and at least two decoupling apertures on which the dispersed light beams are imaged and whose mode field diameters each correspond to the mode field diameters of the associated coupling apertures. Due the enlarged mode field diameter, a larger spectral fraction of dispersed light beams, i.e., light of a larger spectral bandwidth, can be coupled into the decoupling aperture than into the decoupling aperture.
