摘　　要：基于傅里叶变换光谱法原理,针对现有的傅里叶变换光谱仪结构,提出了一种基于干涉光谱法遥测氢的系统设计方案。采用石英碘钨灯作为光源,设计了一套完整的光学能量收集及干涉系统,满足了调校与测量的双重需求。利用LightTools对该系统进行了光学仿真,然后在MATLAB下对模拟接收器接收的光强度值进行了数据处理与分析。结果表明,采用该方案可以很好地对氢气进行远距离检测。最后,阐述了该系统对于其它推进剂检测的适用性。A remote detecting system for hydrogen based on the interferometric spectrometry is presented. Using quartzose tungsten iodide lamp as lighting, an integrated optical device for collecting energy and interfering is designed for adjusting system and measuring hydrogen gas. Then the optical system is simulated by LightTools, the optical intensity received by a receiver is analyzed and processed by MATLAB, and the arithmetic is also set up. The results demonstrate the possibility of this technique in remote detecting hydrogen and the applicability of the remote detecting system in other fuel.
