Novel Temporal Fourier-transform Speckle Pattern Shearing


A method to measure derivatives of displacement using time variation changes in the object together with Fouriertransform analysis in speckle shear interferometry is aimed in this paper. The concept of the method is that the object is deformed continuously and a number of sheared images of the object motion are acquired using a high speed CCD camera. The… (More)
