Abstract

We present the method to obtain four speckle patterns with relative phase shift of ${\pi}/2$ passive devices such as wave plate and polarizer, and calculate the phase at each point of the speckle pattern in shearographic system using Wollaston pin And, we analyzed the phase error caused by wave plates used in the proposed method by Jones matrix.
