Paper Abstract

Frequency spectra are analyzed for two typical speckle-shearing interference recordings - single-aperture speckle-shearing camera (SASSC) and double-aperture speckle-shearing camera (DASSC) to show the fringe variation due to the displacement involved in differentiation. A speckle statistics is then made for filtering system to show the fringe contrastvariation resulting from the object deformation and the aperture of filtering-image system.
