Absorption spectroscopy applied to lidar atmospheric probing
Abstract
Sensitive remote detection of atmospheric pollutant gases can be achieved with optical systems based on the principle of differential absorption of tunable laser radiation. Several types of systems are currently under development and will be discussed at this Conference. Using a broad definition of lidar, they may be classified as active bistatic, active monostatic, or passive monostatic, depending on their mode of operation. This paper is a survey of lidar systems based upon absorption spectroscopy, and their operational characteristics. It describes differences in applications and the type of monitoring information which can be obtained from each.
