Paper Abstract

An IR LIDAR system based on a correlation technique has been designed and is being developed to measure small average concentrations of pollutant or hazardous gases in the atmosphere. The optical source consists of Nd:YAG laser, with a novel SFUR cavity, used to pump a LiNb03 optical parametric oscillator (0P0), which is tunable in the 1.5-4 micron range. Telescope receiving optics and ad hoc electronics complete the system, which is interfaced to a computer to acquire and process the experimental data. The LIDAR is actually designed to detect methane gas concentrations in the ppm range on integration paths of some hundred metres using topographic targets as reflectors and it will be operated on a small truck. Laboratory and field tests of the system are scheduled for the fall of 1986.
