Paper Abstract

A compact, lab-sized dissemination chamber is designed to characterize the fluorescence of aerosols. The chamber, designed according to short-range lidar principles, uses light-induced fluorescence (LIF) with a 355 nm pulsed source. Aerosols concentration inside the chamber can reach hundreds of thousands of ppl. Background noise and irradiance are very low and will allow accurate measurements of spectral signatures. The chamber will serve to study the correlation with spectroscopic data obtained using a long-range lidar system owned by Defence Research and Development Canada (DRDC). Pollens, bacteria, spores, dusts and other atmospheric aerosols will be studied under various environmental conditions. The chamber will be used to create trustworthy libraries for the remote sensing of bio-aerosols.
