MICRORESONATOR FIBER-OPTICAL SENSOR OF CONCENTRATION OF GASES Russian patent published in 1999 - IPC

Abstract RU 2142114 C1

FIELD: environmental control. SUBSTANCE: microresonator fiber-optical sensor of concentration of gases has source of optical radiation in which capacity fiber-optical laser is employed. One butt of fiber-optical laser is mated with microresonator forming Fabry-Perrot interferometer and its other butt is output one and is linked to photodetector. Sensor is fitted with additional microresonator coupled to fiber-optical laser. One of microresonators is fitted with film-sorbent. This film is applied to microresonator placed in measurement arm. EFFECT: enhanced precision and sensitivity. 2 cl, 2 dwg, 1 tbl
