摘　　要：在日益严峻的公共安全形势下,太赫兹技术的飞速发展为反恐安检提供了一项新的有效手段。分析了太赫兹波的特点及其在成像安检中应用的潜在优势,探讨了太赫兹成像安检的主要技术手段,比较了主动式和被动式成像的优劣,并总结介绍了用于安检的太赫兹被动成像和主动成像技术的国内外发展现状,通过对国际主要太赫兹安检成像研究机构的研究历程和近期项目支撑情况的分析,对太赫兹成像安检技术阵列化、多频段、复合式的发展趋势进行了预测,并对太赫兹成像技术在安检和反恐中的应用前景进行了展望。Terahertz science and technology has been rapidly developed in recent years, which make it a capable way to detect person-borne concealed threats. The advantages of terahertz imaging in standoff security inspecting application are introduced according to the characteristics of terahertz waves. A comparison is made between active and passive imaging, which are two main methods for terahertz personnel screening. Then the current status of terahertz imaging research in concealed objects detection is reviewed and commented. It is concluded that terahertz transceiver array, multi-band data fusion and active/passive composition would be the main techniques in future researches. This prediction is based on the analysis in the researches of main institutes in this field and recent programs in Europe. Some key technologies and main trends related to terahertz security inspection are pointed out.
