    The relative motion between the imaging system and the target usually leads to image blurring. We propose a motion de-blurring imaging system based on Fourier-transform ghost diffraction (FGD) technique, which can overcome the spatial resolution degradation caused by both laterally and axially translational motion of the target. Both the analytical and experimental results demonstrate that when the effective transmission aperture of the receiving lens is larger than the target's lateral motion amplitude and even if the target is located in the near-field region of the source, the amplitude and mode of the target's motion have no effect on the quality of FGD and high-resolution imaging in the spatial domain can be always achieved by phase-retrieval method from the FGD patterns. Corresponding results based on conventional Fourier diffraction system are also compared and discussed.
