Abstract

By introducing polarized light detection and polarization indices analyzing, our research has indicated that some certain polarization indices can identify the morphology and absorption of suspended particulates specifically. In this article, we will present the experimental results of polarization indices from three kinds of pollutants discharged from three different sources with respective shape and absorption. A series of simulation results on different shape and absorption will also be given to show the correlation of polarization indices and particulates’ parameters. At last, the particulates from a certain source will be modeled, and the agreement between the preliminary simulations of pollutant sources with the experiment results in a field test will be shown.
