Abstract
The SINBAHD project (1999-2001) had demonstrated the capability of using UV laser-induced fluorescence (LIF) with intensified range-gated spectrometry to detect and characterize bioaerosols from a stand-off position. In the spring of 2005, Defence R&D Canada (DRDC) initiated the BioSense demonstration project, which combines SINBAHD technology with a georeferenced near-infrared lidar cloud mapper. The scope of this technology demonstration project is to build and demonstrate a spectrometric LIF lidar scanning device to detect, map, track and classify bioaerosol threats from multi-kilometre distances. The project includes a variety of field trials using the SINBAHD platform to supply data for the algorithm strategy development and to populate the spectral signature library. In July 2007, SINBAHD participated in a two-week trial held at DRDC Suffield, where different open-air wet releases of bioagent simulants and obscurants were performed. An autoclave and gamma-irradiation killing procedures were performed on Bacillus atrophaeus (BG) samples before they were aerosolized, disseminated and spectrally characterized. Only slight discrepancy in the spectral characteristic of killed versus live samples and none between the two killing methodologies were observed. Correlation assessment between the stand-off sensor SINBAHD and different point sensors, including the slit sampler, was done, allowing an estimation of SINBAHD’s sensitivity in agent containing particles per litre of ai
