Abstract

In the paper, the feasibility of realizing the electronic shearing speckle interference was analysed in theory, the formula describing the light intensity received through the camera target was deduced and the visibility of the fringes formed from electronic interference was analysed. The three methods of electronic shearing speckle, real time, double exposure and real time interval method, are proposed and realized by the authors. The electronic shearing speckle fringe patterns of the contours of the displacement gradient were obtained too.
