On the basis of the M-Z (Mach-Zehnder) interference principle, this paper presents a novel fiber-optic vibration sensor scheme, which can determine the location of vibration events. It simulates and analyzes the signal processing technology for the sensor, achieves fairly good locating performance by increasing signal bandwidth, extending signal duration and improving the SNR and the locating algorithm, and verifies the feasibility of the scheme.
