Abstract

Imaging beyond the memory effect (ME) is critical to seeing through the scattering media. Methods proposed before have suffered from invasive point spread function measurement or the availability of prior information of the imaging targets. In this Letter, we propose a prior-information-free single-shot scattering imaging method to exceed the ME range. The autocorrelation of each imaging target is separated blindly from the autocorrelation of the recorded dual-target speckle via Fourier spectrum guessing and iterative energy constrained compensation. Working together with phase retrieval, dual targets exceeding the ME range can be reconstructed via a single shot. The effectiveness of the algorithm is verified by simulated experiments and a real imaging system.
