這篇論文是關於雙光纖光柵感測系統的研究與應用，主要用於溫度與應力的量測。首先，我們將以光纖光柵理論基礎來討論光纖光柵的製作與其在溫度及應力的應用。在相位光罩程序上，使用載氫與載氘單模光纖來增強光纖本身的感光特性。在光纖通訊系統裡，滲鉺光纖環型雷射是被設計在位能相容的雷射源[30][31]，此雷射源具有高能量、低起始動能(low threshold pump powers)和窄頻寬的特性；第二，根據上述理論，我們建構一個光纖光柵滲鉺光纖環型雷射作為雙光纖光柵感測系統的光源兼參考端，此感測系統以溫度或應力因素導致雙光纖光柵相位差為理論根基，使我們可藉由感測端的光纖光柵反射值來獲得溫度變化的訊息。

This thesis focuses on the study of double fiber grating sensing system and its applications. A double fiber grating sensing system is designed for the measurement of temperature or strain. First, on the basis of the principle of FBGs, the fabrication of fiber Bragg grating and their applications to sensitive temperature and strain are discussed. Using hydrogen loaded and deuterium loaded single fibers to enhance the photosensitivity of the fiber on phase mask process. Erbium-doped fiber ring lasers were designed in optical fiber telecommunication systems as potential compatible laser source [30][31] with high powers, low threshold pump powers and narrow bandwidths. Secondly, according to the theories, we construct an erbium-doped fiber ring laser with a fiber Bragg grating as the optical source and the reference of double fiber grating sensing system. The sensor is based on the phase-mismatched of two fiber gratings produced by temperature or strain. We can get temperature information by the reflection of the sensing fiber Bragg grating.
