摘要：
A digital speckle pattern shearing interferometer with the aid of a diffraction grating as shearing element, is presented. A brief theoretical approach for qualitative purposes is outlined. A comparison with Michelson shearing and phase stepping measurements are presented to show the validity of the proposal. Real time visualization, compactness of the setup and good quality fringes are main advantages.
