摘要

本文使用受挫式內部全反射法（Frustrated Total Internal Reflection）激發表面電漿波及稜鏡耦合Otto組態與電腦軟體來研究不同金屬材質對塑化劑之共振角度與吸收深度之影響。使用表面電漿波光學檢測系統，使得表面電漿波光譜的共振角度和吸收深度會因為不同金屬材質而對塑化劑做出靈敏與即時的反應。再運用表面電漿波光學檢測系統實際所量測出不同金屬材質對塑化劑之數據，並用相關公式及電腦模擬程式反推不同金屬材質對塑化劑溶液相對應之介電常數，進而建立不同金屬材質對塑化劑之介電常數的參考資料庫，作為判別塑化劑存在的依據。除此之外，根據模擬結果顯示，表面電漿波光學檢測系統可清楚判別出塑化劑在不同金屬材質的共振角度與吸收深度之差異性，且銀薄膜解析度最高，也最為靈敏。

This article uses frustrated total internal reflection excitation of surface plasma waves with the prism coupling Otto Configuration and computer software to study the different metal resonance angle and absorption depth of the plasticizer resonance angle. Using a surface plasma wave optical detection system, making the surface plasma wave resonance angle and the absorption depth because of the different metal plasticizer to make sensitive response, and then the actual use of surface plasma wave optical detection system measurements of different metal the plasticizer resonance angle and related formulas and computer simulation program for the thrust reverser different metal materials the plasticizer solution corresponding to the dielectric constant, and thus create a different metal plasticizer mediated dielectric constant reference database as discrimination based on the existence of plasticizer. In addition, the simulation results show that the optical detection of surface plasma wave can be clearly identifies the plasticizer absorption depth of the differences in the metal resonance angle, and silver films the resolution is the highest, most sensitive.
