METHOD FOR OPTICAL DETECTION OF AMOUNT OF GAS ENVIRONMENT COMPONENTS Russian patent published in 2004 - IPC

FIELD: measuring equipment engineering.

SUBSTANCE: method includes placement in gas environment, being radiated from area formed by products of hydrocarbons combustion, of at least two photo-receivers, spectrum sensitivity of at least one of which has maximum in average infrared spectrum range at wave length matching maximal optical density of detected gas component, and spectral sensitivity of another matches different from first one optical density of detected gas component, measurement of signals of each of mentioned photo-receivers with their location at distance from this area, providing for density of radiation on photo-receivers no less than threshold value, and combining direction of maximum spectral sensitivity of photo-receivers with vector from receiver to radiation area, and following detection of amount of searched for component by comparing measured mentioned signals. Aside from that, at least on photo-receiver may be mounted on lee side from radiation area, and as radiation area objects may be used which have thermal and/or radiation exchange with combustion products, also additional radiation area may be used in form of objects having thermal and/or radiation exchange with combustion products.

EFFECT: broader functional capabilities.
