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.
