Abstract: A spectroscopy device that separates input light into a plurality of wavelength ranges. A metal body has a hole or aperture which is open on the upper side. The hole or aperture is formed in a polygonal shape having at least a pair of opposite faces not parallel to each other in horizontal cross-section. Inner side faces of the hole or aperture are finished as mirror like reflection surfaces. Polarized input light inputted from the opening to the hole or aperture is reflected by the reflection surfaces and a standing wave is generated inside of the hole or aperture by self interference, whereby the input light is separated into a plurality of wavelength ranges.

Abstract: A light receiving optical system includes: a relay optical system for converging light to be measured which has been converged on an image plane of an objective optical system on a view angle defining aperture for incidence through the view angle defining aperture. The light receiving optical system has the relay optical system with a relay lens operable to be selectively switched between a first and a second conjugated positions, and a first and a second light flux limiting aperture members disposed in proximity to the relay lens in the case where the relay lens is selectively switched between the first and the second conjugated positions. The relay optical system selectively forms, on the image plane of the objective optical system, an enlarged image and a reduced image of the view angle defining aperture in the case where the relay lens is selectively switched between the first and the second conjugated positions to define an incident light flux through the view angle defining aperture by a first and a second light flux limiting apertures, respectively, in the case where the relay lens is selectively switched between the first and the second conjugated positions. A spectrophotometer has the light receiving optical system.

Abstract: An atomic absorption spectrometer is disclosed which includes a monochromater and an optical path defined by a toric mirror, a flat mirror, a flat mirror, a flat mirror, a toric mirror, and a further toric mirror. The toric mirror directs light through entrance slit of the monochromater so that radiation is reflected from diffraction grating and out exit slit to a detector.

In one arrangement, a magnifying means is also provided which magnifies an image of the aperture at the sample station to increase the amount of radiation which is focused at the sample stage, and which is passed through the aperture to the detector or a focusing element provided by one of the mirrors may be provided for focusing radiation at a location other than sample station so an enlarged out of focus image of the entrance slit is produced at the sample station to increase the amount of radiation which passes through the slit and is received by the detector.

Abstract: A method for measuring scene inhomogeneity includes the steps of directing radiance of a scene into a dispersive spectrometer, and changing the field-of-view (FOV) of the spectrometer, while directing the radiance of the scene into the spectrometer. The method then processes the radiance of the scene to obtain a signal. The method also includes measuring an amplitude of the signal and determining scene inhomogeneity based on the measured amplitude of the signal. The method may include uniformly oscillating the FOV of the spectrometer and, next, obtaining a sinusoidal signal, based on uniformly oscillating the FOV of the spectrometer.

Abstract: Plural electronic or optical images are provided in a streak optical system, as for instance by use of plural slits instead of the conventional single slit, to obtain a third, fourth etc. dimension—rather than only the conventional two, namely range or time and azimuth. Such additional dimension or dimensions are thereby incorporated into the optical information that is to be streaked and thereby time resolved. The added dimensions may take any of an extremely broad range of forms, including wavelength, polarization state, or one or more spatial dimensions—or indeed virtually any optical parameter that can be impressed upon a probe beam. Resulting capabilities remarkably include several new forms of lidar spectroscopy, fluorescence analysis, polarimetry, spectropolarimetry, and combinations of these.

Abstract: The disclosure relates generally to methods and apparatus for using a fiber array spectral translator-based (“FAST”) spectroscopic system for performing spectral unmixing of a mixture containing multiple polymorphs. In an embodiment, a first spectrum of a mixture containing polymorphs of a compound is obtained using a photon detector and a fiber array spectral translator having plural fibers. A set of second spectra is provided where each spectrum of the set of second spectra may be representative of a different polymorph of the compound. The first spectrum and the set of second spectra may be compared, and based on the comparison, the presence of one or more polymorphs in the mixture may be determined.

Abstract: The invention is directed to an arrangement for detecting coatings which are arranged on surfaces of structural component parts or objects and for determining the chemical characteristics and surface properties of these coatings. It comprises a light source for illuminating the coating to be analyzed on the surface of the structural component part and means for imaging the light source on an entrance slit over the surface of the coating to be analyzed. The entrance slit is imaged in a wavelength-dependent manner on a two-dimensional detector unit by a grating. An evaluating unit which is electrically connected to the detector unit serves to evaluate and process the signals supplied by the exposed detector elements of the detector unit.
