Abstract: Disclosed is a Fourier transform spectroscope having a control interferometer capable of facilitating optical axis adjustment and miniaturization by reducing the number of optical elements. Using a first reflection mirror 131 provided with a reflection surface 131a configured to reflect measurement light emitted from a measurement light source 110 toward a beam splitter 140 and a first through-hole 131b extending along an optical axis direction of the measurement light reflected on the reflection surface 131a and a laser light source holding portion configured to hold a laser light source 120 such that laser light emitted from the laser light source 120 is incident to the beam splitter 140 through the first through-hole 131b, optical axes of the measurement light and the laser light are aligned with each other. Since a laser reflection mirror for aligning the optical axes of the measurement light and the laser light of the related art is not necessary, it is possible to reduce the number of parts and facilitate optical axis adjustment and miniaturization.

Abstract: A method for determining spectral calibration data (λcal(Sd), Sd,cal(λ)) of a Fabry-Perot interferometer (100) comprises: - forming a plurality of filtered spectral peaks (P'1, P'2) by filtering input light (LB1) with a Fabry-Perot etalon (50) such that a first filtered peak (Ρ'1) corresponds to a first transmittance peak (P1) of the etalon (50), and such that a second filtered peak (P'2) corresponds to a second transmittance peak (P2) of the etalon (50), - using the Fabry-Perot interferometer (100) for measuring a spectral intensity distribution (M(Sd)) of the filtered spectral peaks (Ρ'1, P'2), wherein the spectral intensity distribution (M(Sd)) is measured by varying the mirror gap (dFP) of the Fabry-Perot interferometer (100), and by providing a control signal (Sd) indicative of the mirror gap (dFP), and - determining the spectral calibration data (λcal(Sd), Sd,cal(λ)) by matching the measured spectral intensity distribution (M(Sd)) with the spectral transmittance (ΤΕ(λ)) of the etalon (50).

Abstract: Interferometric transform spectrometer (ITS) systems and methods of operation thereof. In one example, an ITS system includes a Michelson interferometer that introduces a varying optical path length difference (OPD) between its two arms so as to produce an interferogram, a detector that receives and samples the interferogram, and a scan controller coupled to the detector and to Michelson interferometer. The scan controller controls the Michelson interferometer to vary the OPD in discrete steps such that the detector provides M samples of the interferogram for each of two scan segments. In the first scan segment, the M samples have a uniform or non-uniform sample spacing and the OPD has a first maximum value. In the second scan segment, the M samples have an incrementally increasing sample spacing and the OPD has a second maximum value that is at least twice the first maximum value.

Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

Abstract: A spatial heterodyne spectrometer may employ an integrated computational element (ICE) to obtain a measure of one or more fluid properties without requiring any moving parts, making it particularly suitable for use in a downhole environment. One illustrative method embodiment includes: directing light from a light source to illuminate a sample; transforming light from the sample into spatial fringe patterns using a dispersive two-beam interferometer; adjusting a spectral weighting of the spatial fringe patterns using an integrated computation element (ICE); focusing spectral-weight-adjusted spatial fringe patterns into combined fringe intensities; detecting the combined fringe intensities; and deriving at least one property of the sample.
