Characterization of Soot Aggregates Based on Polarization Modulated Scattering

Analysis of error in soot characterization using scattering-based techniques

“…Therefore, research is underway to extend the analysis to polydispersed aggregates, with the intention to elucidate the effects of polydispersion on soot characterization. Meanwhile, using the scatterometer described in (Hull et al, 2004;Hunt et al, 1998), experimental results have been obtained on soot emitted by diesel engines (Cai, Kranendonk, Ewing, & Ma, 2008). These results are being analyzed to be compared with the simulation results presented here.…”

Characterization of Smoke Particles Using Polarization Modulated Scattering

“…The challenges to discriminate fire and non-fire aerosols using light scattering method represent a major reason for this annoying problem. Research has shown that the polarization properties of scattered light are being exploited to determine the physical properties of aerosols [1,2]. The goal of our research is to study polarized light scattering properties of ensembles of smoke particles.…”
