Paper Abstract

Lidar has been identified as a promising sensor for remote detection of biological warfare agents. Elastic lidar can be used for cloud detection at long ranges and UV laser induced fluorescence can be used for discrimination of bioaerosols against naturally occurring aerosols. This paper analyzes the performance of elastic lidar such as sensitivity, range and angular coverage rate vs. atmospheric visibility, laser and receiver parameters. The analysis of the UV fluorescence lidar is concentrated on estimating the signal strength as a function of range, concentration and optical background level. The performance analysis supports the goal for a practical lidar system to detect 1000 particles/liter at 2-3 km using elastic backscatter and to verify the bioaerosol using fluorescence characterization at 1 km. Some examples of test results with an elastic lidar and a range gated imaging system both at 1.5 μm wavelength are presented together with fluorescence spectra of biological warfare agent simulants measured at an excitation wavelength of 355 nm.
