OPTICAL-ELECTRONIC SPECTRAL GAS ANALYZER Russian patent published in 2007 - IPC G01N21/61 

FIELD: gas analysis, possible use for determining qualitative and quantitative composition of gas mixtures, formed as a result of life activity of organisms or excreted during operation of various devices, internal combustion engines, and also for controlling quality of perfume products.

SUBSTANCE: device contains supply block, connected to output of which are lighting element, fast photo-shutter of input beam, fast photo-shutter of output beam, block of detectors, multi-channel amplifier, and connected to input is control block, through a digital-analog converter; optical trough, connected sequentially to which are fast photo-shutter of output beam, element for spectral dissolution of signal being analyzed, optical system, photo-receiver, multi-channel amplifier, analog-digital converter, control block, while lighting element, fast photo-shutter of input beam and optical trough are positioned on the same optical axis; and optical trough, fast photo-shutter of output beam, element for spectral dissolution of signal being analyzed, optical system, block of detectors are positioned on another optical axis. Optical system contains spectral windows ranging from 1 to ... n for transferring signal being analyzed to photo-detector, made in form of block of detectors, containing from 1 to ... n detectors, making it possible to separately record and transform optical signal being emitted in each predetermined range of spectrum.

EFFECT: expanded functional capabilities, increased resolution.
