Abstract: The present invention relates to spectroscopic methods and systems for collecting electromagnetic radiation from an object using a continuously-spinning wavelength-selecting (CSWS) device, e.g., an interference filter(s) or grating. One embodiment of the invention provides a spectroscopic system for collecting electromagnetic radiation from a target. The spectroscopic system has at least one beam of electromagnetic radiation that interacts with the target. The system includes a continuously spinning wavelength-selecting (CSWS) device, e.g., a continuously spinning interference filter/grating driven by a DC motor, in the path of the at least one beam. The device filters the radiation with regard to wavelength to produce filtered radiation. The system further includes at least one detector in the path of the at least one beam for detecting the filtered radiation.

Abstract: The invention provides spectroscopic systems and spectrometers employing an optical interference filter module having a plurality of bandpass regions. In certain embodiments, the systems include a mechanism for wavelength tuning/scanning and wavelength band decoding based on an angular motion of one or more filters. A spectral processing algorithm separates the multiplexed wavelength-scanned bandpass regions and quantifies the concentrations of the analyzed chemical and/or biological species. The spectroscopic system allows for compact, multi-compound analysis, employing a single-element detector for maximum performance-to-cost ratio. The spectroscopic system also allows for high-sensitivity measurement and robust interference compensation.

Abstract: The invention relates to methods and systems for measuring and/or monitoring the chemical composition of a sample (e.g., a process stream), and/or detecting specific substances or compounds in a sample, using light spectroscopy such as absorption, emission and fluorescence spectroscopy. In certain embodiments, the invention relates to spectrometers with rotating narrow-band interference optical filter(s) to measure light intensity as a function of wavelength. More specifically, in certain embodiments, the invention relates to a spectrometer system with a rotatable filter assembly with a position detector rigidly attached thereto, and, in certain embodiments, the further use of various oversampling methods and techniques described herein, made particularly useful in conjunction with the rotatable filter assembly. In preferred embodiments, the rotatable filter is tilted with respect to the rotation axis, thereby providing surprisingly improved measurement stability and significantly improved control of the wavelength coverage of the filter spectrometer.
