Paper Abstract

Detection of biological warfare agents must be achieved as far upwind of their potential target as possible to provide the time necessary to adopt an effective protective posture. A small-scale fluorescence lidar has been designed and constructed by Dstl. The active element is a solid state Nd:YAG laser, the frequency of which is quadrupled to yield 266nm excitation of 9ns pulses with 40mJ energy. Fluorescence is collected from 300 to 500nm and is divided into 10 channels to investigate discrimination between common fluorescent interferent aerosols and biosimulants. The UV Laser Induced Fluorescence (LIF) LIDAR operated in trials to assess standoff biological detection systems at Dugway Proving Grounds, Utah, USA, participating in both breeze tunnel and open range trials. The collected biological simulant and interferent data has been utilised to train the discrimination algorithm and to assess the system's limit of detection and discrimination ability.
