A field reconstructed from a hologram of a scattering medium is theoretically described. The intensity distribution in the focal plane of a lens positioned behind the hologram is analyzed. Two superimposed patterns are shown to be observed in this plane. The first pattern is in complete agreement with a small-angle spectrum of radiation scattered by an ensemble of particles, and its form is independent of distances from the medium to the hologram and lens. The second pattern represents the Fresnel fringes and depends on the distance between the medium and the hologram. The experimental results are presented.
