The reconstructed images of a double reflective-strip under different shaking amplitudes. Panels (a1)–(a4) are the results when only the test arm is considered under A = 25, 150, 500, and , respectively. Panel (a5) is the corresponding SNR from direct imaging. Panels (b1)–(b4) represents the corresponding results in RGI. (b5) SNR of the ghost-image.
