【摘要】 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。更多还原

【Abstract】 A set of experimental system was designed to verify the feasibility of LIBS for in-situ detection of lunar soil components under lunar environment,synthesized lunar soil was used as detecting object,Nd:YAG laser was used as light source,linear CCD grating spectrometer was used as spectra acquiring system,and vacuum chamber was used to simulate pressure of moon.In order to improve the identification accuracy,high concentration Fe2O3,Al2O3 were employed as certified material.It is demonstrated by the outputs of experiments that LIBS can acquire atomic emission spectra of samples under atmospheric,and qualitatively identify the components forming the samples.更多还原
