Technique of improvement of image reconstructing from registered intensity of diffraction speckle-fields

Technique of improvement of image of scattering object reconstructing with artificial Fourier-hologram is proposed and experimentally implemented. Artificial Fourier-hologram is created by applying on specklegram a system of quasi interference fringes with spatial shift at transition from one speckle to adjacent. The method is based on division of specklegram on fragments. Images from each fragments are reconstructing and then accumulating non-coherent. Image averaged on intensity is forming.
