文摘

Particle size estimation for non-spherical particles by laser diffraction is studied. Scattering by monodisperse needle-like particles is used as case study. Scattering intensity patterns are different for needle-like and spherical particles. Estimating particle size by scattering model for spheres yield artificial modes.
