Analysis of binary mixtures of spherical macromolecules with a Laplace transform method for low light intensity levels.
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, Gamma, 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)) (tau) for scattered light intensities lower than one photoelectron per coherence time.
