Visual perception of humans penetrating turbid medium is hampered by scattering. Various techniques have been prompted recently to recover optical imaging through turbid materials. Among them, speckle correlation based on deconvolution is one of the most attractive methods taking advantage of high imaging quality, robustness, ease-of-use, and ease-of-integration. By exploiting the point spread function (PSF) of the scattering system, large Field-of-View, extended Depth-of-Field, noninvasiveness and spectral resoluation are now available as successful solutions for high quality and multifunctional image reconstruction. In this paper, we review the progress of imaging through a scattering medium based on deconvolution method, including the principle, the breakthrough of the limitation of the optical memory effect, the improvement of the deconvolution algorithm and innovative applications.
