摘要
En 中文
Imaging through scattering media is a fascinating subject in the computational imaging domain. The methods based on speckle correlation imaging have found tremendous ver-satility. However, a darkroom condition without any stray light is required because the speckle contrast is easily dis-turbed by ambient light, which can lead to the reduction in object reconstruction quality. Here, we report a plug-and -play (PnP) algorithm to restore the object through scattering media under the non-darkroom environment. Specifically, the PnPGAP-FPR method is established via the general-ized alternating projection (GAP) optimization framework, Fienup phase retrieval (FPR) method, and FFDNeT. The proposed algorithm is demonstrated experimentally and shows significant effectiveness and flexible scalability, which describe the potential for its practical applications.(c) 2023 Optica Publishing Group
