Laser detection and mapping of biological simulants II. : preliminary concentration and particle shape results / by J. Ho, M. Spence, B.T.N. Evans and G. Roy. : DR52-6/24-1989E-PDF
"The Laser Cloud Mapper (LCM) was designed at DREV to measure and map smoke particle concentrations. This instrument was optimized for larger particles of grenade smoke (>15 mu m). Since most CB aerosol particles are less than 15 mu m in size, it was of practical interest to determine if the LCM could detect CB aerosols. A BW simulant aerosol (bacterial spores) was generated in the field and the LCM was used to measure light scattered by the particles. Various aerosol concentrations were produced to determine low detection limits of the instrument. Preliminary observations indicate that this device was able to detect the simulant aerosol. Lower limits of detection were about 200 to 400 viable spores/liter. Furthermore, with the aid of polarizing filter attachments, the LCM was able to differentiate between the shapes of solvent derived particles (spherical) and spores (elliptical). These capabilities may have important implications for future designs of remote CB aerosol detectors for research and military applications."--abstract.
