摘要
差分光学吸收光谱DOAS主要分为主动DOAS和被动DOAS2种监测技术。介绍主动DOAS技术测量大气污染气体浓度的基本原理以及收发一体的DOAS系统的设计,还对新兴发展可用于区域大气污染监测和大气成分垂直探测的被动DOAS探测技术的基本原理和计算方法进行阐述,并对该类仪器进行简要介绍。
The monitoring technique differential optical absorption spect roscopy（DOAS） is classified into active one and passive one. The paper introduces the basic principle of active DOAS technology monitoring the pollution gas concentration in the atmosphere, describes the design of transceiver. It also stares the instrument principle, operation and calculation method of the newly developing passive DOAS technology which is used for monitoring regional air pollution.
