摘要:太赫兹波是频带在微波与红外之间的电磁波,频率为 -10 THz,由于太赫兹源和探
测技术的不断发展与突破,太赫兹技术在最近几年取得了长足的进步。由于太赫兹波能够穿
透大多数的介电物质,所以该技术可以被用于非金属物质的检测,此外,很多生物大分子的
振动频段落在太赫兹频段内,且太赫兹波不会对人体造成伤害,所以太赫兹技术在医药以及
病理诊断方面较为广阔的应用前景。本文阐述了太赫兹技术在非金属材料无损探测以及生物
医学,特别是组织诊断方面的研究现状。

Abstract: The terahertz wave occupies the region between the infrared and microwave in
ic spectrum, and its frequency is from to 10 THz. As the development of
terahertz source and detecting technology, terahertz has archieved great progress. Most of
dielectric materials are transparent for terahertz wave, so this technology can be used to detect the
non-metallic materials, moreover, the vibration of many biomacromolecules locate in the terahertz
region, and the wave is safe for human, thus terahertz techology has high potential in medi
