Single-shot imaging through scattering medium with a deterministic phase-retrieval algorithm

Abstract

Imaging through scattering layers has a wide range of applications. However, even a thin layer can scatter the light into a random speckle pattern thus difficult to image. Speckle correlation-based methods enable noninvasive imaging of objects hidden behind such layers whereas, still suffer from inaccurate solutions and losing the orientation information of the object. In this paper, we proposed a novel deterministic phase-retrieval algorithm to fully reconstruct the object from its speckle pattern and experimentally demonstrated that the new method can retrieve a high-quality image from a single-shot speckle pattern. Compared to other phase retrieval techniques, it maintains the orientation information correctly in a single reconstruction and is more robust in noisy conditions.
