| Abstract: | A distributed optical fiber sensor is composed of one high birefringence and one signal mode optical fiber.The position of leaking point can be monitored in real time by confirming the time delay between the two measuring signals with the wavelet analysis which is capable of representing the local characteristics of the signal in the time and frequency field. |
