Paper Abstract

The peculiarities of localization of the interference fringes and distribution of their visibility in the localization area at receiving holographic and speckle interferograms radiation with extended reconstructing sources are considered. It is shown that observing the interferograms it is necessary to have the value of relative displacement of the speckles at their recording which is not resolved by the imaging system and does not exceed the volume of spatial coherence of the radiation lighting the hologram and specklegram. Extension of localization area of the interference fringes and spatial distribution of their visibility in dependence on the fact that the imaging system resolves or does not resolve the area of the spatial coherence is determined, respectively, by sizes and shape of the lighting source (and for holographic interferograms by its time coherence as well) and by sizes and shape of the imaging system aperture.
