Paper Abstract

In addition 1:0common usage in atmospheric trace species measurements, the CO laser-based differential absorption (DIAL) and differenüal scattering (DISC) lidar sensor is also an extremely powerful tool for the remote detection, localization, identification and quantification of chemical vapors and liquids composed of the organophosphates that are used in insecticides and in deadly chemical warfare nerve agents such as Satin. The authors have designed, fabricated, and tested a C02 DIAL/DISC lidar sensor system that was optimized for the broad, but distinct spectral features, required for organophosphate detection. This paper describes the system, the field tests that were conducted, test results, and data analysis. Spectral pattern recognition techniques were used to obtain a receiver operating characteristic which relates the probability of detection and false a]ann to concentration-path-length products. Key Words: carbon dioxide, lidar, DIAL, DISC, aerosols, chemical agents, pollution
