摘要
光谱遥感监测是大气环境污染监测领域的一项高新技术，具有其它方法不可比拟的优点，如灵敏度高、分辨率高、多组份、实时、快速监测等．本文介绍了主要几种光谱遥感监测技术：傅氏变换红外光谱（ＦＴＩＲ）技术，差分光学吸收光谱（ＤＯＡＳ）技术， 激光长程吸收技术以及差分吸收激光雷达技术 （ＤＩＡＬ）讨论了它们的测量方式、应用范围、各自的优缺点以目前的发展状态．
Spectroscopic remote techniques are hi-tech in atmospheric pollution monitoring with their special advantages over other methods in many aspects, such as high sensitivity, multi-analytical, fast and on line supervision etc. Four spectroscopic methods are introduced in this paper: Fourier Transform Infrared Spectroscopy (FTIR), Differetial Optical Absorption Spectroscopy (DOAS), Laser Long-path Absorption and Differetial Absorption Lidar (DIAL) based on lasers. Basic measurement principle, operation way, each advantages and shortcomes, and applicaion are also discussed.
