Abstract
A time-interval-statistics method that is based on the measurement of the Laplace transform of the probability function of the time interval s between two successive photoelectrons has been applied to experiment s of light diffusion from low-polydispersity samples from which the sc attered intensity is weak (less than 1 photoelectron/characteristic fl uctuation time). Computer-simulation methods have been used to simulat e intensity fluctuations and positions of individual photoelectrons fo r different experimental situations. The parameters characterizing the diffusion-coefficient distribution function of the sample (mean and i ndex of polydispersity) and their corresponding errors are obtained an d analyzed as a function of the mean intensity and the polydispersity index.
