FIBRE-OPTICAL SELF-EXCITED OSCILLATOR Russian patent published in 1998 - IPC

Abstract RU 2116631 C1

FIELD: measurement technology. SUBSTANCE: given fibre-optical self-excited oscillator may be used to measure various physical quantities ( temperature, pressure, acceleration and so on ). One end face of single-mode light guide 3 of fibre-optical laser 4 forms Fabry-Perot interferometer 5 together with reflecting surface of microresonator 1. Fibre-optical laser is coupled to microresonator by positive optical coupling via Fabry-Perot interferometer. Encoding of output signal in frequency form makes it possible to raise signal-to-noise ratio, sensitivity, to expand dynamic range, to increase conversion factor with use of self-excited oscillator in converters of physical quantities. EFFECT: : improved functional characteristics of converters of physical quantities. 2 dwg
