本論文的研究方向以光纖式麥克森干涉感測器為主，利用光纖雷射作為輸出光源，而在雷射輸出方面，我們使用兩個DWDM薄膜濾波作為特定雷射波段的輸出，藉由兩個波段的雷射輸出，來達到防區擴大的可能性，其中，雷射輸出的兩個波段利用各自所對應的DWDM薄膜濾波到各自不同的感測防區。在實驗上，我們將藉由對光纜上不同的點做敲擊測試，訊號發生波動變化來作為入侵的判斷。

This study focuses on fiber-michelson interferometer sensor. Fiber laser is treated as light source and two DWDM thin-film filter are chosen for output of specific laser wavelengths. Expansion of defense area is achieved with output of two laser wavelengths while distinct wavelengths correspond to different defense area. In experiment, knocking test is employed on several points of fiber cable, variation of signals would be determined as a sign of invasion.
