Digital Shearing Speckle Pattern Interferometry Based on Rochon Prism and Its Application

This paper presents improved digital shearing speckle pattern interferometry based on Rochon Prism. The advantage of this method is that it avoids the shadow noise caused by transmission light, which improves the shearography accuracy. By reducing the angle of divergence and coordinating the measuri...
