中文摘要：

太赫兹波具有许多独特的性质,在很多科学技术领域有着广泛的应用前景。然而,由于水汽对太赫兹波存在强烈的吸收,使得太赫兹波在空气中的传输距离十分有限,限制了太赫兹波的应用,如何实现太赫兹波的远程探测成为太赫兹领域的研究重点。本文介绍了最近出现的THz-REEF和TEA两种远程太赫兹波探测方法,分析了探测过程和探测系统的结构,解释了内在的物理机制,并对其应用进行了展望。

英文摘要：

Terahertz（ THz） wave has many unique properties and broad prospects in many fields of science and technology. However,due to the strong water vapor absorption of THz wave in air,the transmitting distances of THz wave are very limited,which restricts the THz applications. How to implement THz remote detection becomes the focus of the study in the THz field. This paper focuses on the recent remote THz wave detecting method of THz- REEF and TEA,analyzes the detecting process and the structure of the detecting system,explains the intrinsic physical mechanism,and look into the future of THz applications.
