本論文提供一個周界安防之系統，以麥克森干涉儀為感測端，透過DWDM為多波長雷射系統去對應不同防區，來達到即時監控、偵測同時入侵及擴大防區之需求，並結合一些判斷的閾值來降低誤報率，最後，透過不同入侵方式來測試各波長的干涉訊號及誤報率分析。

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.
