Abstract

A dual-CO2 laser differential-absorption LIDAR (DIAL) system has been developed which incorporates both direct detection1 and heterodyne detection of the same LIDAR returns. This system has been used to obtain preliminary measurements of the statistical and temporal properties of the DIAL returns in order to experimentally quantify these properties. Comparison of these results with theory for dual-wavelength operation is currently being conducted. An overview of the system and current status of the experimental measurements will be presented..
