爆炸物及相关混合材料的太赫兹波谱

Terahertz Spectroscopy of Explosives and the Related Compounds

摘要: 对单质环三亚甲基三硝胺(RDX)、环四亚甲基四硝基胺(HMX)、钝感RDX炸药以及多种以单质炸药为主体成分的混合炸药进行了太赫兹谱的试验测量和理论分析。利用太赫兹时域光谱技术(THz-TDS)，给出了炸药样品在0.2~2.5 THz范围内的折射率和吸收系数。结果发现，单质炸药RDX、钝感RDX与六种以RDX为主要成分的混合炸药具有相同的特征吸收峰；单质炸药HMX与混合炸药8702具有相同的特征吸收峰。试验结果表明，利用THz-TDS技术可以对单质炸药以及以其为主体成分的混合炸药进行检测和鉴别。

Abstract: Experimental measurement and theoretical analysis of THz spectrum for two pure materials and some mixed explosive samples were introduced. The refractive index and absorption coefficient of the samples were measured in the region of 0.2~2.5 terahertz by time-domain spectroscopy(THz-TDS). The absorption spectra were obtained correspondingly. The obtained results indicated the THz-TDS technology could identify the different explosives and roughly analyse the main ingredients of the mixed samples.
