A technique for characterization of smoke particles is described. The technique was established through measurements using a polarization modulated angular scanning scatterometer to completely characterize the intensity and polarization of the scattered light. The physical and optical properties of the particles were extracted from the measured data by combining light scattering modeling. Preliminary...
Light scattering models of smoke particles play an important role on the development of photoelectric smoke detection. Aiming at the influence of morphology of smoke particles, spheroid models are introduced to analyze the Stokes scattering matrix of smoke particles, which are lognormal size distributions. Under the condition of random orientations, the effects of refractive indexes and mean size...
