Single-shot non-invasive imaging through highly dynamic scattering media via autocorrelation-domain deconvolution.

Abstract

Imaging through dynamic scattering media remains challenging, because speckle patterns decorrelate during camera exposure. Here, we present a physics-based single-shot non-invasive imaging framework for dynamic scattering media. Enhancing speckle correlation imaging, the dynamically blurred autocorrelation is restored through autocorrelation-domain deconvolution using an analytical blur kernel. The restored autocorrelation is subsequently used for object recovery, with phase retrieval or a physics-informed network under severe degradation. Experimental results on dynamic ground glass and biological slide samples demonstrate robust object reconstruction under dynamic scattering conditions where conventional methods fail.
