title: Laser Doppler velocimetry of particles in a plasma torch.
abstract: A low-cost method of measuring the velocity of particles injected into a plasma torch is described based on direct detection of the Doppler-shifted frequency of laser light scattered by the particles. Velocities ranging from 5 to 60 m/s have been measured for alumina powders using this technique.
