Paper Abstract

Based on speckle multiple-shearing interferometry advanced by Prof. Y.Y.Hung, the paper deals with further study of its principles and proposes several kinds of new wedges, as well as analyzes the frequency spectra of double-exposure specklegrams. Discussions are also made on second order statistical characteristics of speckles when non-coherent superposition is effected for two speckle fields with no correlation at all. In order to raise the cut-off frequency of Fourier's filtering system, it is recommended in the paper that non-coaxial system be employed in place of coaxial system commonly used. Formulas for computation of changes in phase difference in speckle shearing interferometry have also been derived, and results of computations are compared with those of Prof.Hung.
