Abstract

It is shown that the current autocorrelation function of scattered light from aerosols situated in gas that has macroscopic motion will be strongly affected. The exact autocorrelation function for steady flow is calculated. Experimental results verify the calculated results. Using the measured results and the calculated function one can find the single-particle correlation function and the diffusion coefficient.
