Abstract

A novel two-frequency dynamic light scattering system (TF-DLS) and differential heterodyne en face laser Doppler velocimeter (LDV) are proposed and setup. The power spectrum of the heterodyne beat signal is detected whereas the width of power spectrum and shift of central frequency are measured simultaneously. These are able to provide the particle sizing and its tangential velocity in suspension. Finally, the localization ability of TF-DLS/LDV system on en face velocity measurement was discussed.
