A white light-based light-scattering technique for particle sizing

A novel light-scattering technique is presented in this paper. Unlike the traditional methods, white light is used as the light source, and the light-scattering signals are collected within only one solid angle, from which the particle size and its distribution can be obtained by an inversion calculation. The basic principle is discussed. Results of the computer simulation and experimental studies made with monodisperse polystyrene latex spheres and polydisperse industrial samples are given.
