Paper Abstract

We propose a new technique of speckle interferometry which can measure a dynamic phase change in large deformation. In this method, we use a continuous tracking approach of the deformation we proposed previously, and apply a new technique, which can measure the large deformation by eliminating a noise term not correlating to the deformation, to the approach. A 450 μm in-line deformation of an aluminum plate was successfully tracked in an experiment.
