摘要
近年来,世界各国都对太赫兹科学给予了很大的关注,相应的太赫兹辐射源和探测器的研究和发展速度加快,太赫兹技术应用也取得了实质的进展,特别是太赫兹波在空间天文观测和大气遥感中的应用。介绍了近些年发展起来的几种探测太赫兹电磁波的新技术及目前发射或建立的多种亚毫米波、太赫兹波探测系统在天文观测和大气遥感中的具体应用,显示了太赫兹波探测技术在遥感领域中的巨大应用前景。
During the last few years, terahertz science has become a research hotspot in the world, Tne studies on new terahertz sources and detectors and their development are accelerating. Furthermore, some terahertz techniques have been put into practice in the field of space astronomical observatory and atmospheric remote sensing. In this article, several new terahertz detection methods and some working terahertz detectors for astronomic observatory and atmospheric remote sensing are introduced. The successful uses of these novel techniques and instruments have clearly shown the huge exciting application prospect of terahertz in remote sensing.
