Particle Image VelocimetryUsed to map the velocity

of a flow field cross sectionLaser creates a light

sheet through the flowCameras take quick

series of imagesCorrelation yields

ProcessingResolve stereoscopic images

Produce a 3D plot of the field from two stereoscopic images.

Cross-correlationFind movement of each

particle within the 3D plotsProduce a velocity mapping

Join each plane mapping to form a full area mapping Image courtesy of
