Abstract

A photon correlation Laser Doppler Anemometer system for the simultaneous measurement of sub-micrometer particle size and velocity is introduced. From the results of Monte Carlo simulations it is shown that the FFT of the auto-correlation function of the detected scattered intensity contains the information on particle size. Experimental results on polystiren latex particles of 100 nm size are discussed.
