Abstract

A variation of particle image velocimetry is described that uses a third, unequally spaced, laser pulse to resolve the direction of a velocity vector extracted from an image. The use of a CCD camera makes the complete process electronic and therefore quicker and more convenient. The analysis method produces correlation functions with fewer noise correlations, resulting in less vector drop-out.
