Abstract: This article reviews a number of recent PDA developments designed to either improve accuracy or extend the technique in measurement range or measurand. Many of these developments have depended on improvements in the computation of light scattering from small particles and initially several of these improvements will be discussed. The sensitivity of the dual-mode PDA to particle sphericity will be discussed, followed by possibilities for the sizing of oscillating particles/droplets. Finally, some remarks will be directed to the dual-burst technique and its use in novel optical systems.

Keywords: phase Doppler anemometry, light scattering, particle sizing
