摘要

周界入侵感測系統是一部置在戶外環境外圍或敏感區域四周的設施，目的在於實時監控、偵測和定位入侵者，以評估策略及因應。周界入侵感測系統在整個安防系統中舉足輕重，其表現影響所保護的區域安全甚鉅。由於傳統的周界入侵感測系統有其不足之處，是以先進的周界入侵感測系統需求孔急。
本論文旨在綜覽雙馬赫詹德干涉式周界入侵感測系統，提出系統的模擬模型，並根據模擬結果就系統設計提出建議。本論文首先描述光纖中的相位調變方法以清楚地闡述系統的運作原理。再敘述雙馬赫詹德干涉式周界入侵感測系統，包括其系統架構、運作原理及系統中的雜訊源與偏振光誘發效應。為預估系統的表現及研究系統的特性，本論文也提出一個適合以MATLAB軟體模擬，受雜訊影響的系統模型，並呈現、討論模擬結果。最後，本論文呈現系統之實驗結果，並與模擬結果比較。
與基於不同之技術研發而成的周界入侵感測系統比較，雙馬赫詹德干涉式周界入侵感測系統有許多優勢。相信此系統假以時日必定會成為最好的周界入侵感測系統之一。

A perimeter intrusion detection system (PIDS) is a device that deploy in an outdoor environment at the boundaries or around sensitive areas in order to monitor, detect, and locate intruders in real time for assessment and reaction. PIDS plays a vital role in the whole security program such that the performance of PIDS affect the facility safety severely. Since traditional PIDSs have some shortages, an advanced PIDS is always in great demand.
This thesis aims to provide an overview of the dual Mach-Zehnder interferometric perimeter intrusion detection system (DMZIPIDS), propose a simulation model for the system, and give advice on the design of the system in accordance with simulation results. In this thesis, the basic optical phase modulation mechanisms in optical fibers are described at first to clearly elaborate how the system works. Then, an introduction to the system, including its system structure, theory of operation, and noise sources as well as polarization-induced effects in the system, is described. A noise-involved and MATLAB-based simulation model of the system is proposed in order to predict the performance and study the characteristics of the system. Simulation results are presented and discussed. Experimental results of the system are presented and compared to the simulation results in the end.
In comparison with other PIDSs that use different technologies, DMZIPIDS has many advantages. It is believed that, given time, DMZIPIDS would be one of the best PIDSs.
