Abstract: The present invention causes measurement light, emitted from an object and to be measured, to enter a fixed mirror and a movable mirror forming interfering light between the measurement light reflected by the fixed mirror and measurement light reflected by the movable mirror. Change to the intensity of the interference light of measurement light is obtained by moving the movable mirror unit, acquiring the interferogram of measurement light. Reference light of a narrow wavelength band included in a wavelength band of the measurement light enters the fixed mirror and the movable mirror, forming interference light of the reference light. The movable mirror is moved to correct the interferogram of measurement light, which is at the same wavelength as the reference light in the measurement light, and the reference light, and a spectrum of the measurement light is acquired based on the corrected interferogram.

Abstract: Calibration of an arbitrary spectrometer can use a stable monolithic interferometer as a wavelength calibration standard. Light from a polychromatic light source is input to the monolithic interferometer where it undergoes interference based on the optical path difference (OPD) of the interferometer. The resulting wavelength-modulated output beam is analyzed by a reference spectrometer to generate reference data. The output beam from the interferometer can be provided to an arbitrary spectral instrument. Wavelength calibration of the arbitrary spectral instrument may then be performed based on a comparison of the spectral instrument output with the reference data. By appropriate choice of materials for the monolithic interferometer, a highly stable structure can be fabricated that has a wide field and/or is thermally compensated. Because the interferometer is stable, the one-time generated reference data can be used over an extended period of time without re-characterization.

Abstract: An Electro-Optic Imaging Fourier Transform Spectrometer (EOIFTS) for Hyperspectral Imaging is described. The EOIFTS includes an input polarizer, an output polarizer, and a plurality of birefringent phase elements. The relative orientations of the polarizers and birefringent phase elements can be changed mechanically or via a controller, using ferroelectric liquid crystals, to substantially measure the spectral Fourier components of light propagating through the EIOFTS. When achromatic switches are used as an integral part of the birefringent phase elements, the EIOFTS becomes suitable for broadband applications, with over 1 micron infrared bandwidth.
