Non-invasive single-shot wide-field imaging through dynamic thick scattering media base on a fully developed speckle pattern

Abstract

Imaging through scattering media has always been a challenge to be solved in optical applications. The speckle autocorrelation method has achieved great success in non-invasive single-shot imaging through dynamic thin scattering media, but the field of view (FOV) is still limited by the optical memory effect (OME). Recently, there have also been methods focused on imaging through thick scattering media, but they either require prior knowledge of the samples or multiple speckle patterns. Here, we present an imaging method that enables non-invasive single-shot imaging through dynamic thick scattering media without the limitation on the FOV imposed by the OME. In the proof-of-principle experiments, we used a fully developed speckle pattern that combines a classical phase-retrieval algorithm to achieve imaging through a three-dimensional dynamic ∼2.5 mm thick chicken breast tissue, which exceeded the OME by ∼57 times. In addition, our method can also achieve lensless wide-field imaging through dynamic thin scattering media. We anticipate that our method will enable non-invasive single-shot wide-field imaging in currently inaccessible scenarios.
