摘要
A distributed fiber optic intrusion detection sensor is proposed, in which a nonbalanced Mach-Zehnder interferometer is used as phase demodulator, and an optical time domain reflectometer is used as a position detector. The experimental results concluded that the positioning error of +/- 25m can be achieved along an 8.8-km single mode fiber.
