新型光学长程吸收池的仿真设计研究

为了解决传统的长程光学吸收池设计中镜面利用率低导致反射次数少的问题,根据传输矩阵理论,开展了离散型Herriott池的结构参数设计研究。基于MATLAB数值计算模拟详细研究了吸收池内光线的传输次数与机械结构参数、光线的入射位置及入射角之间的依赖关系。仿真结果为实际应用中设计便携式长程光学吸收池提供良好的参数和模型借鉴作用。

Study of New Type Optical Multi-pass Optical Absorption Cell

To solve the problem of the low reflection number induced by the poor utilization of the mirrors in traditional long path optical absorption cell,the structure parameter design of the astigmatic Herriott cell is car-ried out in this work, according to the transmission matrix theory. The relationship of the beam transmission number in the optical absorption cell with the structure parameters,the position of the incident beam and angle of the incident light are analyzed in detailed by numerical simulation based on MATLAB software.The simula-tion results provide a good reference for the design of the portable long path optical absorption cell in practical application.
