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.
