Abstract :
The method to obtain four speckle patterns with relative phase shift of pi/2 by passive devices such as two waveplates and a linear polarizer, and to calculate the phase at each point of the speckle pattern in shearographic system with a Wollaston prism and the polarization elements is presented, and the feasibility of the proposed method is theoretically demonstrated by Jones vector
