Abstract

A Laplace transform method for low intensity scattering experiments, presented in a previous paper [ Opt. Lett. 13, 637 ( 1988)] for monodisperse samples, has been generalized to dilute mixtures of spherical scatterers of different sizes. A theoretical model for the errors in the determination of the width, Γ, of the spectrum scattered for each kind of particle has been developed. A computer simulation of an experiment has helped us to compare the proposed method with that of the measurement of g⁽²⁾ (τ) for scattered light intensities lower than one photoelectron per coherence time.
