Abstract

A novel sensing system of locating and monitoring ordinary disturbance signals in long distances is proposed.A feedback loop is constructed within all-fiber interferometer and single fiber is firstly employed as the sensing fiber

and by using fast Fourier transforming and wavelet transforming as the method of processing signal

the position of a random signal is successfully determined.By fulfilling the experiment

some very good frequency spectrum images are obtained

and the system’s relative error is below 0.08 %

so its function of locating and monitoring can be realized.
