Noninvasive Imaging Through Scattering Media with Enlarged FOV Using PSF Estimations and Correlations

Abstract

Noninvasive imaging through scattering media using memory effect (ME) normally suffers from the failure of imaging when the object is beyond the ME region, limiting its field of view (FOV). Herein, a method to enlarge the FOV is proposed by utilizing point‐spread‐function (PSF) estimations and correlations. For the first time, to the best of the knowledge, it is successfully demonstrated that a whole object or multiple objects with the right relative positions and orientations, although they are beyond the ME region, can be noninvasively well reconstructed using the proposed method, which suggests that it can realize noninvasive imaging through scattering media with enlarged FOV. Further, it is experimentally verified that the method can promote one of the previous works, making it capable of noninvasive super‐resolution imaging through scattering media beyond the ME region. The technique paves the way to noninvasively visualize objects behind scattering media beyond the ME region with enlarged FOV and unprecedented clarity.
