Abstract

Measurements of scattering power and SNR as a function of detection angle were carried out employing a differential heterodyne laser Doppler velocimeter (DLDV) and a white light fringe image velocimeter (WFIV). Particle diameters of 0.481 μm and 5.7 μm were employed for the DLDV and WFIV, respectively. In general, the measurements are in excellent agreement with calculations based on Mie theory.
