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.

Cameron Tropea: He received his Bachelors and Masters of Applied Science at the University of Toronto (Eng.Sci.) before moving to the University of Karlsruhe, Germany, where he received his Dr.-Ing. in 1982. After holding a researcher assistentship at the University of Erlangen-Nuremburg, a guest professorship at the University of Waterloo, Canada, and an industrial position, he moved to his current position as head of the Institute of Fluid Mechanics and Aerodynamics at the Technical University of Darmstadt, Germany. He has been active in Laser Doppler and Phase Doppler development work throughout his academic career and applies these instruments to investigate complex turbulent flows and atomisation and spray processes.

Nils Damaschke: He studied electrical engineering and received his Dipl.-Ing. at the University of Rostock, Germany, 1997. During this period, he worked in the research area of Laser Doppler and Phase Doppler developments, especially in the field of light scattering simulations. He is presently carrying out a Ph.D at the Technical University of Darmstadt with Prof. Tropea. His work is in the area of optical particle measerement of nonspherical and inhomogeneous particles.
