Abstract: A multiband spatial heterodyne spectrometer for determining spectra in first and second wavelength bands has a beamsplitter configured to split incident light and to direct the incident light upon a first and a second diffraction grating. The gratings are configured for Littrow reflection of incident light of the first wavelength band at a first order and Littrow reflection of incident light of the second wavelength band at a second order. Light reflected by the first and the second diffraction grating forms diffraction patterns imaged by an electronic camera. A dispersive device separates the imaged interference patterns onto separate groups of pixel sensors corresponding to the wavelength bands. A processing device receives information from the detector and computes spectra therefrom. The second diffraction grating is split spatially or temporally to provide two different responses, so the system can disambiguate spectra. In embodiments, the spectrometer computes hyperspectral images of a target.

Abstract: A tunable interferometric scanning spectrometer is provided. In one aspect of the disclosure, the interferometric scanning spectrometer splits incoming light beams among different optical paths in the spectrometer, recombines the light beams from the different optical paths to produce combined light beams, detects intensities of the combined light beams across a focal plane (e.g., with a sensor array), and calculates a spectra based on the detected intensities and a filter function that is a function of optical path difference (OPD) between the optical paths. In one aspect, the filter function varies across the focal plane. In another aspect, the spectrometer comprises a rotatable dispersive element (e.g., glass plate) in one the optical paths and/or a moveable mirror in the other optical path. In this aspect, the spectrometer may be adjusted away from zero OPD by rotation of the dispersive element and/or displacement of the mirror.

Abstract: A fast switching arbitrary frequency light source for broadband spectroscopic applications. The light source may operate near 1.6 um based on sideband tuning using an electro-optic modulator driven by an arbitrary waveform generator. A Fabry-Perot filter cavity selects a single sideband of the light source. The finesse (FSR/ΔνFWHM) of the filter cavity may be chosen to enable rapid frequency switching at rates up to 5 MHz over a frequency range of 40 GHz (1.3 cm−1). The bandwidth, speed and spectral purity are high enough for spectroscopic applications where rapid and discrete frequency scans are needed. Significant signal-to-noise advantages may be realized using the rapid and broadband scanning features of this system in many areas of spectroscopy, e.g., process monitoring and control, reaction dynamics, and remote sensing (e.g., greenhouse gas monitoring, biological/chemical agent screening).
