V类限制性采样返回的自动化监测系统研究
Research on automatic monitoring system of class V restricted sample return
摘要
Abstract
Mars sample return is the first class V limited sample return mission in deep space exploration.In the process of receiving and unsealing extraterrestrial samples,it is necessary to realize bidirectional isolation of earth and mars samples by means of the sample disposal isolation protection device,which also puts higher requirements on the automatic monitoring system of sample disposal isolation protection device.Therefore,based on tunable diode laser absorption spectroscopy technology,an automatic monitoring system suitable for the structure of the double-walled sample handling isolation protection device is proposed,which is used for the synchronous real-time monitoring of ambient temperature,humidity and oxygen content inside the working chamber.In order to further improve the detection sensitivity of the system,an improved stepped variable curvature optical multipass cell with simple structure and easy adjustment is proposed.The optical simulation model is used to simulate the specular spot distribution of the optical multi-pass cell.The simulation results show that,in the studied examples,the effective absorption path of the improved stepped variable curvature optical multi-pass cell can reach 225.6 m,which is 2.2 times higher than that of the traditional Herriott optical multi-pass cell.It verifies the validity of the proposed optical multi-pass cell structure,and can provide reference for the development of automatic environmental monitoring system in Class V limited sampling return.关键词
