Abstract: An interferometer, preferably of the Michelson type, is disclosed, in which the reflectors associated with the interferometer arms are stationary, and scanning is accomplished by displacement of a single wedge-shaped refractive element in one of the arms. The reflectors are preferably retro-reflectors rather than flat mirrors in order to minimize the effects of chromatic dispersion. A Moire scale may be used to measure the position of the wedge-shaped refractive element.

Abstract: A voltage is applied to a liquid-crystal variable retarder that monotonically changes a retardance and changes a first derivative with respect to time of the retardance of the liquid-crystal variable retarder over a time period. An interferogram of light passing through the liquid-crystal variable retarder is measured during the time period.

Abstract: A technique and device to determine the spectrum of electromagnetic radiation in a certain range of wavelengths comprising: splitting said radiation into more than one beam; let these beams counter-propagate in a Sagnac-type ring interferometer; and imprinting a wavelength-dependent angular tilt onto the wavefront of each beam by at least one dispersive element which preferably is a transmission grating or grism; and re-combining the multiple beams on a detector that exhibits spatial resolution and can therefore resolve the fringes formed by interference; and perform the mathematical operations to determine the spectrum of said radiation from the obtained interferogram, wherein the dispersive element is mounted on a stage providing linear and/or rotational movement.

Abstract: Described herein is a hyperspectral imaging system in which a polarizing beam splitter, a Wollaston prism, an optical system, and a plane mirror are arranged on an optical axis of the imaging system. An imaging detector is provided on which radiation is focused by an imaging lens. The Wollaston prism is imaged on itself by the optical system and the plane mirror so that translation of the Wollaston prism in a direction parallel to a virtual split plane of the prism effectively provides an optical path length difference that is the same for all points in the object field.

Abstract: A Fourier-transform interferometer with self-apodization compensation comprises at least one pair of mobile prisms forming a plate with thickness which varies at the same time as an optical path length difference is itself varied. The prisms are displaced using a mobile system with a single degree of freedom, comprising two support elements and at least two rotatably hinged levers. The interferometer is adapted to be installed on board a satellite, for spectral analysis of a radiation originating from the Earth's surface.

Abstract: A Fourier transform spectrometer for use, among others, for sensing gases or liquids includes two polarizers, a birefringent optical component interposed between the two polarizers and a detector. Light from an extended source is substantially polarized by a first of the two polarizers, split into divergent beams by the birefringent optical component, and again caused to converge by the birefringent optical component so that, after passing through a second of the two polarizers, the light forms an interferogram in a plane behind the birefringent optical component where the detector is situated. The Fourier transform spectrometer is thereby provided with a way of forming an interferogram of the light from the extended source without a lens or a second birefringent optical component. This improves the field of view of the spectrometer and is likely to reduce its cost.

Abstract: A planar optic sensor for measuring the optical absorbance spectrum of a side variety of substances in situ comprises a planar waveguide Mach-Zehnder interferometer having a reference path and a sensing path. The sensing path of the waveguide is exposed to the sample under test, the sample interacting with the guided light via emanations from the light as it propagates through the sensing path. The reference path of the waveguide is provided with a heater that linearly varies over time the refractive index of the reference path material, in this manner varying the optical path length of the reference path. Fourier spectroscopic techniques are applied to compare the spectrum of a white light source without a sample present in the sensing path to the spectrum of the white light source in the presence of a sample in the sensing path, as the optical path length of the reference path is swept over time. From these data the absorption spectrum of the sample is determined.
