氧氣感測器在最近幾年被廣泛地應用在各個領域，如：國防工業、隧道工程、環境監控…等。這是由於光纖式氧氣感測器具有多項優點，如：非侵入式、不與氧氣反應、體積小、靈敏度高、反應速度快、具有高度的彈性設計、可在惡劣的環境中進行長時間的監測。由於應用層面的廣泛，因此理想的感測器必須適用於各個操作溫度。
　　本實驗使用普遍的合成技術-溶膠凝膠法(sol-gel)合成出微孔薄膜(microporous film)，而將螢光指示劑-PtTFPP (Pt(Ⅱ) meso-Tetra (Pentrafluoropheny) Porphine) 侷限於微孔薄膜的孔洞中，再將此薄膜被覆於光纖尖端而製成光纖式氧氣感測器，並校正此感測器於不同溫度下之特性。最後，並提出一簡單之溫度補償之方法，依據此溫度補償方法得出之數據，可以設計出溫度補償機制，而此溫度補償機制將隨溫度的變化並同時進行補償而不需知道量測時的溫度值，使此溫度感測器能夠應用在更廣泛的使用範圍。

　　In recent years, the oxygen sensors have been applied in various areas, such as national defense industry, environment monitor, etc. In all of the various types of oxygen sensors, the fiber-optic sensor on optical type is more interesting. The advantages of the fiber-optic sensor are noninvasive, no consume oxygen or participated in any chemical reactions, small size, high sensitivity, high response time, long-term using in abominable environment. Because of the large-scale application, the ideal oxygen sensors have to be applied in the various temperatures usefully.
　　In this study, an indicator, Pt(Ⅱ) meso-Tetra (Pentrafluoropheny) Porphine, was trapped in the porous film synthesized by sol-gel processes. The porous xerogels were coated on the end of an optical fiber for sensing. We calibrate the oxygen sensor at various temperatures and build an alternative method for compensating the temperature dependence oxygen sensor. The temperature compensation method varied with temperature, so that, we need no to know the temperature as measuring and apply the sensor at various environment.
