Paper Abstract

Light scattering in atmosphere can change optical polarization properties. Analysis and Measurement on interaction of polarized light with atmospheric particulates can provide important information to evaluate the atmospheric composition and conditions. In this paper, we propose a polarization character focusing on the evaluation of soot content in the air, based on our polarized photon scattering simulation program. The simulation results demonstrate how the polarization parameter at a specific scattering angle can identify the soot particles from the other air pollutants. Compared with nonpolarization optical measurement, polarization characterization can enhance the contrast of distinguishing different type particles and also can be applied in a wide particle size range.
