Abstract

多波長光纖雷射 防區型入侵偵測 麥克森干涉儀 Multi-Wavelength Fiber Laser Perimeter Intrusion Detection Michelson Interferometer
This paper proposes a perimeter intrusion detection system which employs multiple differently-located Michelson interferometers as detection schemes for different area intrusion detection. The proposed detection system going with preset thresholds of signal amplitude and frequency could achieve real-time intrusion detection, providing defenses against trespassing. A multi-wavelength fiber laser as a light source incorporating our proprietary intrusion detection technique performs well in multi- area intrusion detection. It reduces the false-alarm rate with appropriate threshold setting. We analyze false-alarm rate through different intrusion ways.
