Abstract

This paper proposed a three-component fiber optic seismic sensor array based on Michelson interferometer for intrusion detection of subway tunnel. A high-resolution phase interrogation technique based on phase generation carrier (PGC) method are used to provide a high accuracy detection system of intrusion signals. The field test of intrusion detection based on three different types of machines shows the feasibility of the system.
