摘要：
A method of reconstruction of the spatial phase distribution and the image of a scattering object from a recorded speckle pattern of the diffraction field has been developed and verified on test objects. The proposed method is based on an assumption that, for objects of a certain class, the phase difference between adjacent speckles in the far zone is equal to pi. Digital records of Fourier speckle patterns and the corresponding digitally reconstructed images are presented.
