腔增强/衰荡光谱应用于气溶胶消光检测研究进展

腔增强/衰荡吸收光谱技术，是目前应用最广泛的气溶胶光学特性原位测量方法之一，由于其原位、实时特性，测量过程中气溶胶状态不会发生改变，测量具有代表性，近些年来已经开始作为各种仪器综合比对实验中使用的参考标准。在经过近30年的发展后，相关技术发展日益成熟。本文将对腔增强/衰荡吸收光谱技术的发展及其在气溶胶光学特性测量方面的应用研究做简要的回顾。

Monitoring Aerosol Extinction with Cavity Enhanced/Ring-Down Spectroscopy : A Brief Review

Cavity-enhanced/ring-down spectroscopy is one of the most widely used spectroscopy technique for the high sensitivity, real time, in-situ measurement of the aerosol extinction coefficient. The nature suspended state of the aerosol is not changed during the measurement. After nearly 30 years development, the techniques were well developed. The instrument based on cavity-enhanced/ring-down method was served as a standard instrument for the intercomparisons with other optical measurement instruments. In this paper, the development and the application of cavity-enhanced/ring-down spectroscopy for aerosol extinction measurement were briefly reviewed.
