Optical Techniques for the Remote Detection of Biological Aerosols

Abstract

Laboratory and remote detection experiments with optical techniques demonstrated the feasibility of remote fluorescence detection of biological aerosols. Laboratory measurements of fluorescence response of five types of bacteria were best characterized by excitation spectra. A lidar field experiment verified the principle of fluorescence detection of biological aerosols under atmospheric conditions and enabled evaluation of achievable remote sensing performance. Performance calculations indicated that an optical detection of 14 cells per liter of air could be achieved at a range of 2 kilometers at sea level in midlatitude locations.
