【摘要】 太赫兹(THz)及几十THz的超远红外波段在近十年来受到了广泛的关注,各种产生、探测和应用研究已经成为当前光学和光电子领域最热门的研究方向之一。利用气体等离子体产生和探测THz相比其他方法不仅能得到更强更宽频谱的THz,而且在THz探测频谱范围和动态范围上更具有很大的优越性。本文详细介绍了目前最前沿的几种利用激光诱导气体等离子进行THz甚至超远红外电磁波的波谱和远程探测方法,发现这一领域拥有广阔的应用前景,当然更有很多方面亟待研究。更多还原

【Abstract】 Terahertz(THz) and even ultra infrared waves have drawn many attentions in the past ten years.And their sources,sensors and applications have become one of the hottest research areas. Ultra-fast laser pulse induced gas plasma have showed incomparable advantage in intense and broadband THz generation as well as broad band and large dynamic range THz detection.In this paper, we will emphasize in detection and introduce sever ways to complement THz and even broader wave detection,especially remote sensing.We found broad application perspectives in this field,and also many challenges.更多还原
