Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: A method for spectral interpretation in absorption spectroscopy uses a nonlinear spectral fitting algorithm for interpretation of spectral features in complex absorption spectra. The algorithm combines two spectral modeling techniques for generating spectral models to be used in the curve fitting process: a line-shape model and a basis-set model. The selected models for all gas components are additively combined using a least squares minimization, allowing for quantification of multiple species simultaneously.

Abstract: Systems, methods, and devices relating to optical imaging systems for gathering data on atmospheric trace gas emissions from a satellite. An optical system used in the satellite has a Fabry-Perot interferometer coupled to a suitable telescope. The interferometer is a wide angle Fabry-Perot interferometer which creates a fringing pattern in concentric circles with each fringe being a different wavelength on the imaging system. A filter is used with the optical system and allows multiple adjacent modes in a selected spectral range to pass through the interferometer to the imaging system. Each pixel in the imaging system collects light at multiple wavelengths within the selected spectral range. The optical system gathers multiple images of the target area allowing light from the target area to be collected at multiple different wavelengths. Different absorption data for different atmospheric trace gases can be gathered in a single satellite pass over the target area.

Abstract: An optical sensor includes an array of pixels configured to convert photons into electrons for forming an image. A tunable filter assembly is optically connected to the array of pixels for passing an adjustable bandwidth of photons to the array of pixels. The tunable filter assembly includes a first mirror defining an optical axis and a second mirror spaced apart from the first mirror along the optical axis. A first electrode is mechanically connected to the first mirror and a second electrode is fixed relative to the second mirror. The first and second electrodes are positioned relative to one another to adjust the position of the first mirror with respect to the second mirror when a voltage is applied across the first and second electrodes to tune the spectral bands being passed through the filter assembly to the array of pixels.

Abstract: Methods and apparatus for video rate or near video rate quantitative imaging of tissue physiological and morphological properties from visible/NIR light spectral images obtain rapid multi-spectral reflectance images by illuminating with a series of spectra containing multiple narrow wavelength bands. An iterative light-transport based inversion algorithm may be applied for correcting the intensity of the spectral images from the geometry/coupling effect as well as from the scattering amplitude distortions. The method can produce video rate absorption as well as scattering spectral images that can be further analyzed very rapidly, using matrix-based rapid inversion algorithms to produce more detailed quantitative images containing information relevant to tissue physiology and morphology.

Abstract: A fiber grating demodulation system for enhancing spectral resolution by finely adjusting an imaging focus mirror, includes a laser pump source, a wavelength division multiplexer, a fiber Bragg grating, a diaphragm, a slit, a collimating mirror, a light splitting grating, an imaging focus mirror, a linear array detector. The laser pump source, the wavelength division multiplexer, the fiber Bragg grating are connected in sequence, the wavelength division multiplexer is connected to the diaphragm. Light emitted from the laser pump source is multiplexed by the wavelength division multiplexer and then enters the fiber Bragg grating, a reflection spectrum of the fiber Bragg grating enters the slit of the fiber grating demodulation system as injected light. After passing through the slit, the injected light is reflected by the collimating mirror, the light splitting grating, and the imaging focus mirror in sequence, and is finally converged to the linear array detector.
