Paper Abstract

The mobile demonstrator for biological aerosol standoff detection has been designed and built to test and develop reliable optical methods for the identification of biological aerosols in a 10 km range. Disciplines such as agriculture, defense and security are increasingly concerned with distinguishing certain classes of biological particles from remote distances. The instrument combines backscatter channels for 3 laser wavelengths, 2 nitrogen Raman channels, depolarization and fluorescence channels with 2 ultraviolet excitation wavelengths. Aerosol size distribution, particle shape and refractive index as well as fluorescence excitability by different laser wavelengths and spectral fluorescence information are the distinguishing variables for the identification of unknown biological aerosols.
