摘　　要：为更好地设计基于不同材料、不同制作工艺文物的最佳保护方案,文物保护科技人员首先需要选用最有效的无损检测方法对文物进行全面检测。太赫兹波具有光子能量低、对非金属和非极性物质有较强穿透性、可同时获得脉冲电场振幅和相位信息、较好的抗干扰能力等独特性质,使其在诸多无损检测方法中脱颖而出。本文系统综述了太赫兹技术在文物无损检测应用中的最新研究进展;阐述了不同类型文物材料的太赫兹光谱特征、太赫兹成像检测技术原理和特点;指出了太赫兹无损检测技术对不同类型文物进行无损检测的技术关键点,列举了太赫兹技术在文物科学领域最成功和最具代表性的应用实例。最后展望了太赫兹无损检测技术在文物保护领域的发展趋势。To design the optimal protection scheme for cultural relics of different materials and production techniques,the cultural heritage scientists are in constant search of the most effective nondestructive testing method for the overall survey of the cultural relics.Due to the unique properties of terahertz wave’s low energy,strong penetrability for non-metallic and nonpolar substances,simultaneous measurement of amplitude and phase information,strong anti-interference capacity,etc.,terahertz technology has been gaining an edge over other conventional nondestructive testing methods.In this review paper,the latest progress of terahertz technology applied in nondestructive testing of cultural relics are introduced,and the terahertz spectra characteristics of various cultural relics materials are illustrated.The principle and characteristics of terahertz imaging detection technology are expounded.The key issues in the application of terahertz nondestructive testing technology for various cultural relics are discussed,and the most successful and representative application examples of terahertz technology in cultural relics science are listed.Finally,we present the developing trend of terahertz nondestructive testing technology in the field of cultural relics.
