GEAR MEASURING ATMOSPHERIC POLLUTION Russian patent published in 1997 - IPC

FIELD: measurement technology, spectroscopic analysis of microimpurities in gases, predominantly in atmosphere, both under laboratory conditions and in the field by measurement of reflection factor of surfaces of specimens. SUBSTANCE: proposed gear includes radiation source, flat mirror, two semitransparent flat plates so oriented that they form together with flat mirror Fabry-Perot resonator, radiation detector with electron unit of signal processing. Flat mirror is rigidly joined to base and with peripheral zone of front side to semitransparent plates of Fabry-Perot resonator through thermal decouplings. Flat mirror has cooling system of material having high heat conductivity placed so that its working zone is separated from peripheral one by compensator of mechanical stresses. EFFECT: expanded application field, enhanced operational authenticity. 2 dwg
