    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.

    Abstract: An apparatus for measuring fluorescence of potable liquids contained within an optical quartz cell includes a deep UV laser or a compact UV LED that generates a light beam. A UV blocking and visible light transmitting optical filter reduces out-of-band emission from the LED. The optical quartz cell is between a pair of plane mirrors so that light from the light source travels through it several times. A concave mirror collects a fluorescence signal and has a common optical axis with a lens. The common optical axis is normal to an optical axis of the light beam. The concave mirror and lenses are positioned on opposite sides of the optical quartz cell. A fluorescence detector is in optical alignment with the concave mirror and the lens. A boxcar averager is in electrical communication with the fluorescence detector. Optical wavelength selection of the fluorescence emission uses optical filters or a spectrometer.

    Abstract: A spectral measurement device includes an optical band-pass filter section having a spectral band of first to n-th wavelengths (n is an integer of 2 or more), a light receiving section, a correction operation section, and a signal processing section. When an m-th wavelength band (1≦m≦n) is an interest wavelength band, and a k-th wavelength band (k≠m and 1≦k≦n) other than the m-th wavelength band is a non-interest wavelength band, the optical band-pass filter section functions as a m-th band-pass filter corresponding to the m-th wavelength band and a k-th band-pass filter corresponding to the k-th wavelength band.

    Abstract: A multi-channel array spectrometer combines a spectral measurement system and a reference detector which measures photometric or radiometric qualities. High accuracy photometric or radiometric measurement of a wide dynamic range can be achieved by correcting measurement results of the reference detector with a spectral correction factor. The multi-channel array spectrometer comprises a bandpass filter wheel holding a set of bandpass filters and an open hole. The wheel is placed between an entrance slit and gratings. A test light beam passes through a turret of the bandpass filters. The test light beam can be precisely measured band by band. The spectrometer can also quickly and accurately measure a plurality of test light sources having similar spectral characteristics by using the stray light correction factor.

    Abstract: A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.
