Abstract
A new method of automatic fringe analysis for particle image velocimetry (PIV) data reduction is presented. The technique is based on calculating the positions of coincident peaks in the cross-correlation of pairs of separated parallel lines of data in the fringe pattern. Preliminary results show that an efficient automatic data reduction system can be realized using this approach.Keywords
