Abstract

Scattering medium is always a problem to be overcome in traditional optical imaging technology. In recent years, a speckle intensity correlation technique has been proposed to achieve high quality reconstruction of targets hidden in the scattering medium. Unfortunately, the imaging field of view (FOV) of this technology is seriously limited by the optical memory effect (OME) range. Here, we propose an iterative point-spread-function deconvolution (IPSFD) method to reconstruct multiple targets. According to the reversibility of the deconvolution algorithm, the IPSFD method starts from a small known target, and estimates the adjacent targets and point-spread-functions continuously by the iterative deconvolution algorithm, and finally reconstructs all targets within around three times the optical memory effect range. Theoretical and experimental results confirm that our method can achieve multi-target reconstruction of the single-shot large FOV speckle pattern. This method may have potential in practical applications biomedical imaging, astronomical imaging, and atmospheric turbulence imaging.
