| 摘 要： | 提出了一种用于长距离定位监测的新型传感系统。该系统在全光纤干涉系统中构建反馈环,首次采用单芯光纤作为传感光纤,结合快速傅里叶变换和小波变换对信号进行处理,实现了对随机扰动源的监测定位。实验获得了清晰的频谱图像,系统定位的相对误差小于0.08%,可实现定位监测功能。

| 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. |
