摘 要:In this paper,we propose the novel system of multipoint *** sensors of measurements are chirped Bragg grating and the interrogation of sensors is sub-carrier *** wavelength division multiplexing technique is used for addressing a network of FBG sensors and the time-division multiplexing technique is used for multipoint *** the system,the modulation frequency of 200 MHz is *** range of dectetion is from 0 to 900μεand the resolution is 12με. The time of the sensor response is about 1ns.
