Paper Abstract

Target object image would deteriorate into unrecognizable speckle pattern when encountering with scattering media. It’s necessary to reconstruct the target object image from captured speckle. In this paper, a method combining correlation method and oversampling smoothness is proposed. It is used for target object reconstruction from scattered speckle pattern. The reconstruction is based on the Fourier transform of the target object. The Fourier amplitude of the target object can be calculated through an inverse Fourier transform of the autocorrelation of captured speckle pattern. The Fourier phase can be recovered with oversampling smoothness method. Experiments were used to comparing the proposed C-OSS method with the C-ERHIO method. The results indicate that the proposed method improves the reconstruction with lower background components than the other. The proposed method can also be applied to optical image encryption et al.
