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 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.

Abstract: A device according to the present invention includes an interferometer which produces interference fringes from light received from a light source. The interference fringes are imaged onto a photo-diode array which transforms the imaged interference fringes into a single set of electric signals. The single set of electric signals is digitized and stored as a group of consecutive data points which represent an interferogram signal containing a DC component. The data points are processed to obtain moving average values representing the DC component of the interferogram signal. The moving average values are subtracted from the data points to obtain a clean interferogram signal which is Fourier-transformed to obtain a spectrogram of the light source.

Abstract: A laser referencing system is disclosed which is used in a refractively scanning interferometer. The interferometer optics comprise a fixed wedge-shaped prism having a beamsplitter surface, a movable wedge-shaped prism, and two corner cube reflectors. A laser clocking beam enters the interferometer on a path below the infrared analytical beam, and leaves the interferometer on a path above the infrared beam. Quadrature control of the laser beams is used to control the ends of the scanning sweeps, eliminating the need for a third, "white light" interferometer beam. ZPD alignment is accomplished by horizontal adjustment of the fixed beamsplitter prism. The interferometer optics are supported three-dimensionally in a cast shell.
