本論文是利用受挫式全反射方法配合 Kretschmann 組態和 Otto 組態激發表面電漿波對游泳池氯的研究。Kretschmann 組態為磷化鎵的稜鏡-金屬薄膜-待測物,Otto 組態為磷化鎵的稜鏡-待測物-金屬薄膜。 本研究方法除了根據光學受挫式全反射方法與激發表面電漿波之 Kretschmann 組態與 Otto組態外,也參考了Kretschmann於1971年以及Otto於1968年後,陸陸續續所發表之論文的理論、量測金屬表面電漿波的光學實驗架構,其中參考光學實驗架構中的雷射光及三層反射率公式配合MATLAB軟體進行模擬研究,並對整個模擬結果作深入分析與探討。 本論文中研究主要針對游泳池的氯粉和氯錠溶於水時以及氫氯酸在Kretschmann組態與Otto組態中,在不同的金屬薄膜厚度(金、銀),所產生的表面電漿波共振角之差異性。
This research studied chlorine from a swimming pool which was stimulated surface plasma wave using frustrated total reflection type method with Kretschmann configuration and Otto configuration. The Kretschmann configuration consists of prismatic-metal film-DUT of gallium phosphide; the Otto configuration consists of prismatic-DUT-metal film of gallium phosphide. The simulation of the study was conducted according to the frustrated total reflection type method to stimulated surface plasma wave with Kretschmann and Otto configuration. The optical experiments whose architecture referred both of these configuration measured metal surface plasma waves using three reflectance formulas and MATLAB software in this paper. This study is mainly to find the difference of resonance angle of surface plasma waves of hydrochloric acid in the water of a swimming pool which was dissolved chlorine powder or tablets under Kretschmann and Otto configuration for different thickness of metal film layer (gold, silver).
