摘要
基于气体近红外选择性吸收理论和Beer-Lambert定律,研究了硫化氢气体的拉曼散射特性,同时采用宽带光源光谱吸收检测技术对H2S气体进行检测。将自聚焦透镜作为光纤准直透镜和聚焦透镜,并将其应用于透射型气室。同时,提出了在透射式气室中将多对自聚焦透镜组串联使用以增加吸收光程的方法,该方法可以明显提高气室的检测灵敏度。通过分析实验测得的H2S吸收曲线,得到系统的灵敏度为3.672×10-4 μW/(μL/L),分辨率为122.5 μL/L。
Abstract
Based on the theory of selective absorption of gas in the near-infrared region and the Beer-Lambert law, Raman scattering characteristics of hydrogen sulfide gas are researched. Meanwhile, a broad-band light source is used to detect the concentration of H2S gas. Self-focusing lenses are used as collimating or focusing lens for transmission gas cell. A method using cascaded GRIN lens to increase the optical-path length is presented, and the detection sensitivity of the gas cell is greatly increased by this method. By analyzing the experimental curves of hydrogen sulfide absorption, it is shown that the system sensitivity is 3.672×10-4 μW/(μL/L), and the resolution is 122.5 μL/L.
