无损检测技术是一种不破坏零件或材料，可直接在现场进行检测的技术，广泛应用于样件的质量评估。太赫兹波具有量子能量低，对大多数非极性物质透明，兼具频谱性和成像性等特点。作为一种新型技术，太赫兹无损检测已经成为现有无损检测技术的有力补充。文章介绍了太赫兹成像系统的工作原理，阐述了基于连续太赫兹成像的无损检测技术在实际样件测试中的应用。实验测试结果表明，一些样件利用太赫兹无损检测技术可测得其内部缺陷。

Nondestructive inspection is a technique which can be conducted directly in the test field with no damage to the parts or materials, and is widely used in evaluating the quality of sam-ples. Terahertz waves (THz) have the characteristics of low energy and, for most non-polar substanc-es, good transmission. As a new technique, THz nondestructive inspection has become a powerful supplement for existing nondestructive inspection technology. In this paper, the basic principle of THz imaging systems is introduced, and the application of continuous THz nondestructive inspec-tion in actual sample testing is reviewed. Experimental results show that the inner defects in various samples can be detected using THz techniques.
