Abstract
An optical technique for analyzing particle image velocimetry data has been demonstrated on a variety of particle patterns from actual flows and from similar translate diffuser experiments. The technique uses point-by-point illumination of the particle image and two subsequent 2D FFTs to produce an autocorrelation pattern of the particles from which the particle displacement is determined. The dynamic range in the technique''s configuration is about 30:1, with reasonably good processor speed.
