Abstract
In this paper we report the development and test of a high sensitivity fiber Bragg grating (FBG) seismic sensor system for intrusion detection application. A high sensitivity FBG seismic sensor is designed and its sensitivity is above 1000pm/g. Unbalanced Michelson interferometer and Phase generated carrier(PGC) algorithm are adopted by the demodulation system. The system noise is below 10(-3) pm/ root Hz and the minimum detectable seismic signal is below1 mu g root Hz. The FBG seismic sensor has a maximum detection range of about 70 meters for human and about 200 meters for small wheeled vehicle.
