摘要：

The optical fiber intrusion sensor is investigated in the configuration of an optical time domain reflectometer using coherent interference of Rayleigh backscattering in a single mode fiber. When the modulation pulse width was 4usec, the spatial resolution of this intrusion senosr was about 400m, the signal to noise ratio was about 3.3 and the bandwidth was about 30.5Hz.
