Differential cross sections of nuclear reactions often exhibit characteristic oscillations in the angular distribution originated from an interference two indistinguishable processes. Here we propose a novel method to visualize origins such oscillations. This is achieved by taking Fourier transform scattering amplitudes, following idea wave optics. We apply this elastic $^{16}$O+$^{16}$O and $^{18}$O+$^{18}$O at energies above Coulomb barrier. The former system shows strong due nearside-farside interferences, while are largely suppressed latter stronger absorption. show that image systems corresponds double-slit single-slit problems quantum mechanics, respectively.
