Because of the strong scattering effect of scattering media, the traditional optical imaging systems cannot be used to image and track objects behind these media. To address this problem, this paper proposes a method for tracking and reconstructing the moving objects behind a scattering medium. Based on the theory of optical memory effect of scattering media, the point spread function of a scattering imaging system is solved using prior information. The axial scaling relationship of this point spread function is used to determine the axial displacement and the cross-correlation of the reconstructed moving objects is used to determine the lateral offset. An experimental system based on the proposed method also achieve the fast reconstruction and motion tracking of an object behind the scattering medium. The proposed method can track object displacement by collecting only continuous speckle images of the displaced object. Thus, this approach does not require specific devices but provides excellent results, which is helpful in the application of imaging moving objects through scattering media in the field of biomedicine.
