Digital optical holography with virtual reference wave

Possibility of scattering object image reconstruction bis digital Fourier - specklegram (intensity distribution of scattered field in far area of diffraction, without use of coherent referent wave) is considered. Action of referent wave formation of hologram structure with system of carrying interference fringes, is realized a posteriori at the stage of numerical processing of digital specklegram with using of representation about binary distribution of objective field phase in various speckles. Setups for digital specklegram recording, information features of hologram structure, possibility of its synthesis and procedure of numerical image reconstruction bis digital specklegram of diffraction field and reconstruction system of carrying fringes are discussed.
