光谱学 太赫兹 特征吸收 爆炸物 特征谱 spectroscopy terahertz characteristic absorption explosive characteristic spectra
摘要
对单质炸药环三亚甲基三硝胺(RDX)、钝感RDX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(THz)谱的实验测量和理论分析。利用太赫兹时域光谱技术(THz-TDS)给出了这些炸药样品在0.2～0.5 THz范围内的折射率和吸收系数; 并与理论模拟的结果进行比较。结果表明, 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, 实验测量与理论模拟结果符合很好, 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识别。
Abstract
Experimental measurement and theoretical analysis of terahertz spectrum for one pure material and some mixed explosive samples are introduced. The refractive index and absorption coefficient of the samples are measured in the region of 0.2～2.5 THz by time-domain spectroscopy(THz-TDS). The absorption spectra are obtained correspondingly. Results indicate that the THz-TDS technology can identify the different explosives and roughly analyse the main ingredients of the mixed samples.
