Effects of Particle Nonsphericity on Light-Scattering

  • Peter W. Barber
  • Steven C. Hill


Characterizing particles by analyzing their light scattering properties is of interest in many diverse fields. The most common measurement is particle size. Measurements of particle refractive index and shape are also of interest. Most optical sizing methods are based on the assumption that the particles are spherical.
