摘　　要：太赫兹波(THz)是频率介于毫米波与红外光之间的辐射,近年来,自由电子激光器与超快技术的发展,为THz提供了稳定的发射源,人们对THz波的研究越来越深入,对其在各领域尤其在公共安全方面的应用广泛关注。本文概要介绍了THz波的主要性质和产生原理,并从安全检测,毒品与爆炸物鉴别三方面介绍了THz波在安全方面的应用前景。Terahertz wave is the radiation whose frequency is between millimeter wave and infrared. Recent years, the developments of free electron laser and ultra fast technology provide the steady source for THz radiation. More and more people become interested in the application of terahertz especially in the public security fields. The main characters of THz and the principle of generation are introduced.The potential application in the aspect of people screen, drug detection and exploder detection is showed.
