为了验证激光诱导离解光谱技术在月球环境条件下月壤成分现场探测的可行性,设计了一套实验模拟装置,以合成月壤样品为检测目标,Nd:YAG激光器为光源,线列CCD光栅光谱仪为光谱的采集系统,真空罐模拟月球气压环境。用高纯度Fe2O3,Al2O3作为标准参考光谱样品提高识别精度。实验结果说明在模拟环境下利用激光诱导探测手段能够采集到样品的原子发射光谱,并完全可以定性识别物质中含有的成分。
In order to verify the feasibility of laser-induced dissociation spectroscopy in the on-site detection of lunar soil components under lunar environmental conditions, a set of experimental simulators were designed to detect lunar soil samples. Nd: YAG laser was used as light source and line CCD grating spectrometer For the spectral acquisition system, the vacuum tank simulates the atmosphere of the moon. Using high-purity Fe2O3, Al2O3 as a reference sample to improve the recognition accuracy. The experimental results show that using laser-induced detection method in a simulated environment can acquire the atomic emission spectrum of the sample and fully identify the components contained in the material.
