    Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled into different modes during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

    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: The present disclosure is directed to imaging device, systems, and methods for collecting optical data for use with spectrometers. An imaging device configured in accordance with one aspect of the disclosure includes a lens configured to introduce light into the imaging device along an optical path, and an image sensor spaced apart from the lens and configured to receive at least a portion of the light along the optical path. The imaging device further includes a filter assembly positioned between the lens and the image sensor, and a reflector or mirror carried by the filter assembly. The filter assembly is configured to move the reflector between first and second positions. In the first position the reflector is at least partially aligned with the optical path and reflects at least a portion of the light to a corresponding light input for a spectrometer. In the second position the reflector is positioned outside of the optical path.

    Abstract: An image capture device includes an imaging assembly having a spectral sensitivity tunable in accordance with a spectral capture mask. A pre-capture captures a sample image of a scene using the imaging assembly tuned by a first spectral capture mask. A second spectral capture mask is constructed by calculations which use image data of the sample image. The second spectral capture mask is constructed to tune the spectral sensitivity of the imaging assembly so as to adjust respective capture parameters for different objects in the scene. The second spectral capture mask is applied to the imaging assembly. An image of the scene is captured with the second spectral capture mask applied to the imaging assembly.
