Experimental results on the influence of a diffraction size of a reflector on the mean intensity of a beam in its axis when propagating along correlated and uncorrelated paths through an inhomogeneous medium are presented. The mean intensity on the correlated path, as compared with uncorrelated one, is shown to increase when the reflector dimensions are multiple of even number of Fresnel zones and to decrease when dimensions are multiple of odd number of zones. At the increase of the reflector dimensions and turbulence strengthening, the mean intensity on the axis of beams propagating along both correlated and uncorrelated path approaches magnitude of the intensity of a spherical wave.
