Abstract : The development of a fully integrated whole field measurement device is discussed. The system relies on the use of electronic imaging technology, and an improved method of particle tracking to yield up to 500 vectors in less than 20 seconds. The technique is based on a modified form of cross-correlation, resulting in increased data reliability and a reduction in processing time. The system performance is fully quantified using real and simulated data. Finally its application to a convection flow is described. (Author)
