Fig. 1. Experimental schematic of motion deblurring imaging system based on FGD technique.

Fig. 2. Phenomenological explanation of motion deblurring imaging system based on FGD technique.

Fig. 3. Experimental results in different lateral motion amplitudes when z₁ = 160 mm. (a)–(d) are the FGD patterns when the maximum lateral motion amplitudes deviating from the optical axis are 0, 0.5, 1, and 2 mm, respectively. (e)–(h) are the corresponding results of conventional Fourier diffraction at the same motion amplitudes as (a)–(d), which is achieved using the test path and removing the RGGD in Fig. 1. The upper right corner is the image in the spatial domain recovered by the phase-retrieval method from the corresponding diffraction patterns.

Fig. 4. Experimental results in different axial motion amplitudes. (a)–(c) are the FGD patterns when the target’s axial motion ranges around z₁ = 160 mm are ±10, ±20, and ±40 mm, respectively. (d)–(f) are the corresponding results of conventional Fourier diffraction at the same motion amplitudes with respect to (a)–(c). The other descriptions are the same as Fig. 3.

Fig. 5. Experimental demonstration of motion deblurring when the target’s maximum lateral motion amplitude is 2.0 mm and its axial motion range around z₁ = 160 mm is ±40 mm. (a) The FGD patterns and the reconstructed image in the spatial domain; (b) the case for conventional Fourier diffraction.
