| Abstract: | Based on analyzing the speckle field s characteristic, the tracking method of digital speckle correlation using the sequential dynamical speckle patterns was presented. This method can bridge the gap that the ordinary speckle correlation does not suit the large deformation measurement, and increase the applied fields of digital speckle. Through this method, the large-scale dynamical displacement can be measured and the process of deformation in surface can be analyzed. |
