Paper Abstract

A novel location algorithm based on zero-crossing analysis is introduced in this paper to reduce the location error and processing time of dual Mach-Zehnder interferometric (DMZI) fiber perturbation sensor. The algorithm can extract highfrequency part from original signal and obtain perturbation location using cross correlation in a very short process time. By extracting high-frequency signal, the algorithm can also acquire a low perturbation location error. Experiment results show that the perturbation location error only has 10 m and the processing time is less than 0.13s in the case of 10MHz sample rate.
