The method presented in this paper enables the retrieval of the shape of two objects hidden behind a thin scattering medium, with one object stationary and the other gradually moving. The feasibility of this method is demonstrated through theoretical analysis and experiments.
The shape of two objects hidden behind a thin scattering medium is retrieved by the presented method. One of the two objects keeps stationary, while the other one is supposed to be gradually moving, and the Euclidean distance between them is always beyond the range of the 3D optical memory effect. We capture two speckle patterns to image the two isolated objects by using a developed speckle-differential-based strategy and the traditional speckle autocorrelation technique. The feasibility of our method is demonstrated by theoretical analysis and a set of experiments. (C) 2021 Optica Publishing Group.
