Point-wise analysis of rotating aperture method for speckle photography
In this paper, we make a point-wise analysis of a specklegram made by rotating aperture method for speckle photography. The Young s pattern is generally not equal spaced straight fringes, but curved fringes according to the dynamic process of displacements. In this paper, the meaning of the pattern is explained, theoretical analysis and experimental demonstration are presented.
