Abstract
According to the filtering theory, we derive a functional expression of the optical field distribution, which is the filtering image of the intensity spectrum of the double-exposure speckle pattern passed through the filtering aperture in Fourier transform plane. Further, an affect on formed fringes to be yield by filtering due to the shape of the filtering raperture is discussed. An effect due to filtering is not appeared on the fringe pattern, it only affects the envelope and contrast distribution of the frienges, this influnence seems weak, however, it offeres the theory foundation, if we try to obtain an optimum quality of the fringe pattern.
