Abstract
The binary correlation method is revised to measure 3D-velocity field. The revised binary correlation method for 3D measurement is also aimed to work on a personal computer as the 2D version was. Because of that reason, the new version was developed by considering minimizing the memory occupation and shortening calculation time.
By introducing a overlapped volume function and uniform paticle image, cross correlation coefficient between two 3D particle-patterns could be evaluated easily.
The performance of the new method is examined by personal computer simulation, and found to be promizing in the actual measurement.
