基于太赫兹光谱技术的爆炸物类危险品检测

Detection of Explosives by Terahertz Spectroscopic Techniques

太赫兹(THz)光谱技术识别爆炸物类危险品是一种极具竞争力的新型安检方法。总结了不同研究机构的爆炸物指纹谱数据,建立了可供参考的数据库;讨论了棉布、塑料、皮革、涤纶和硬纸板等常见材料覆盖下隐蔽爆炸物的检测状况;介绍了远距离探测爆炸物的最新研究进展。最后,分析了实战场景中应用THz光谱技术检测爆炸物需要面临的混合爆炸物、复杂环境条件和远距离探测等主要问题,并对未来的发展趋势作了展望。

Terahertz spectroscopic techniques have been regarded as competitive methods for the identification of explosives and related compounds.The explosives fingerprint data of various research institutions are reviewed to establish reference databases.The detection of explosives hidden under some materials including cotton,plastic,leather,polyester,cardboard etc.is discussed.The latest research advances of the remote detection of explosives are described.Furthermore,the major issues faced with mixed explosives,complex environment conditions,remote detection on THz detecting explosives in the actual scene and so on have been analyzed.The future trends in a preliminary outlook are pointed out.
