Abstract

We propose and experimentally demonstrate a technique for the single-shot imaging through a scattering medium based on speckle correlation assisted digital in-line holography. The proposed method enables the reconstruction of the complex amplitude information of the object located at any arbitrary planes behind the scattering medium by retrieving the digital in-line hologram. The technique exploits the potential of speckle correlation approaches and machine learning schemes for the efficient reconstruction of complex amplitude information from the digital in-line hologram scrambled in the speckle pattern. The complex amplitude imaging capability of the proposed technique is theoretically introduced and experimentally validated by imaging various standard and unknown objects.
