title: Single-particle velocity and trajectory measurements of microscale inhomogeneities in unstable airflows.
abstract: In unstable airflows, it is found that often the seed particles used to make laser Doppler anemometry measurements of fluid velocities follow complicated trajectories in even very small fringe volumes. A technique to obtain maximum particle-trajectory information from the scattered light signal is described. The use of this technique to measure fluid-motion characteristics in regions of unstable flow down to 10-microm scale inhomogeneities is described.
