Abstract

In optical system with double Fourier-transformation and with an illuminating spatially modulated laser beam, scatterer in an entrance plane and a random phase object in spatial-frequency plane the process of formation of average intensity interference fringes in the plane of the image is considered. It was shown that the optical system can work in shift interferometer mode. The analytical expressions for the contrast of the image of fringes as functions of object's statistical parameters and parameters of an illuminating beam (fringe spatial frequency and beam aperture) are obtained. It is established that in coherent and incoherent optical systems with scatterer in an entrance plane the contrast of the image of sine-wave fringes depends similarly on parameters of object in spatial-frequency plane and parameters of optical system.
