Paper Abstract

Shape is a key parameter of aerosol particle. Light scattering and imaging via microscope are conventional measurement ways for detecting aerosol particle shape, but their conclusion can't be certified by themselves. A new self-consistent method combining scattering and imaging is tried. A concentric hollow spherical chamber is the core portion to get signal, where flying single aerosol particle along diameter perpendicular to horizontal plane intersects with laser beam at the chamber centre. Photo of aerosol particle is gained by CCD after amplified, simultaneously, scattering of the same particle is transferred by optical fibers and conversed by PMT. The intensity and polarization of scattering by single fibre cotton are analysed according self-programming wave theory, and the reason for difference of signal is declared compared with photos by CCD. The result shows that the method is reliable.
