TL;DR: In this article, a distributed fiber disturbance sensor based on a Sagnac interferometer is proposed, which is used for coupling an arm, synchronously a delayed fiber ring is added, namely a delayed-fiber ring is superposed in a single SAGA to form two SAGAC interferometers with different length, the time division multiplexing of the two SagnAC interferers with different lengths is realized by the propagation of optical pulses in the interferer, and the positions of disturbing points are calculated to realize the distributed sensing of the disturbance

TL;DR: In this paper, an optical fiber distributed disturbance sensor, and a method, by which the disturbance sensor can achieve disturbance positioning, is described. But, the method is characterized in that light path output signals from an interferometer are divided into three equal paths of light, pass through analyzers with polarization angle differences of 0 DEG, 60 DEG and minus 60 deG respectively, enter a photo detector and are converted to electrical signals therein, are subjected to the square summing calculation after being conditioned by filtered signals and amplified signals, get rid of the DC amount by filtration
