THz光谱技术在炸药及其相关材料检测中的应用进展

太赫兹（THz）光谱技术近年来在航空航天、生命科学、安全检测等领域的应用进展迅速.由于许多炸药及其相关材料在THz波段具有特征吸收，许多非金属、非极性材料对THz 波是透明的，且THz波具有低能性，THz光谱技术在安检中具有巨大的应用潜力.文章介绍了国际上THz光谱技术在炸药及其相关材料研究中的现状和进展及文章作者在炸药及其相关材料THz光谱研究方面的成果，讨论了THz技术应用于安全检测领域面临的挑战.

Recent progress of THz spectroscopy in the detection of explosives

The newly developed technique of THz spectroscopy has made much progress in aviation, life science and safety inspection. Many explosives have characteristic absorptions in the THz region, and non－metallic and non－polar materials are transparent to THz waves. In addition, THz radiation has low photon energies and does not cause photon ionization so it has great potential in safety inspection. This paper reviews the status quo of THz spectroscopy of explosives, including our investigations. The hurdles and challenges of THz technology in safety inspection are discussed.
