Speckle photography with radially scanning aperture
In this paper, a new method of speckle photography-radially scanning apertire method is proposed, and theoretical analysis and experimental results are presented. This method has the advantage of recording the whole dynamic process of an object on one speckle photogram. The information of deformation in the direction of x and y axis and of 45° at any moment can be obtained in the form of isothetio fringes by whole field filtering.
