Abstract

Infrared differential absorption lidar (IR DIAL) techniques allow remote sensing of low concentrations of gases in the atmosphere from distances up to several kilometers. Field tests were carried out with two nearly Identical coherent CO2-laser based DIAL systems with coincident beam paths to prove data validation for rapidly fluctuating gas concentrations. Statistical analysis of the time-fluctuating lidar signals was used to determine the demonstrated sensivity limits (range and minimum detectable path-integrated concentrations) for the DIAL systems.
