利用光受挫式內部全反射法激發表面電漿波於氯及鹵甲烷的量測

Using the Excitation Surface Plasma Waves of Optical Frustrated Total Internal Reflection to the Chlorine and Halogen-methane Measurement

指導教授 : 李正民

摘要


本論文是根據光受挫式內部全反射方法利用稜鏡的耦合來激發表面電漿波,量測出氯氣與鹵族甲烷(氟甲烷、氯甲烷、溴化甲烷、碘甲烷)之共振角度。研究過程中,我們使用Otto組態與KR組態分別對氯氣與鹵族甲烷做特別的分析研究,經由鹵族氣體的微小介電常數差異,透過模擬實驗分析後,仍然可以準確的判斷出待測氣體之共振角度與吸收的深度,所以利用此光學式量測系統來量測可說是具有相當之靈敏性。藉由量測出之氣體共振角度與尋找出的氣體間隙或金屬薄膜厚度之關係,期盼未來能夠實際的製作出監測系統,應用於工業安全上對人體有害的氣體的偵測,經由監測系統的防護,適時的提出警報,以維護勞工在其職場上的安全,並減少工作意外的發生。

This research used the optical frustrated total internal reflection by the coupling of prisms to excite surface plasma waves to measure the resonant angle of the chlorine and Halogen-methane (including the fluoromethane, chloromethane, bromomethane, and iodomethane). During the process of this research, the Otto configuration and KR configuration are used to proceed the special analysis on the chlorine and Halogen-methane, and through the simulative experimental investigation into the tiny variation of dielectric constants of Halogen gas, the resonant angle and depth of absorption of the to-be-investigated gas can be accurately measured. Thus, this optical measuring system can be confirmed with high sensitivity. The measurement of the resonant angle and findings of gas gap or metal film are expected to practically apply to the industrial safety investigation into harmful gas channels in the future. Through the protection of the investigating system, the warning information can be given in time, the labor’s safety in the work place can be ensured, and the occurrence of work accidents can be prevented.
