The optical model potential, which reflects an overall feature of the nuclear property and reaction dynamics, has been widely adopted to describe the nucleus-nucleus interaction phenomenologically. Experimentally, knowledge of the optical potential can only be learned in the vicinity of a sensitive radius. In this study, the notch technique was applied to extract the radial sensitive regions of the tightly bound system $^{16}\mathrm{O}+^{208}\mathrm{Pb}$ and weakly bound systems $^{9}\mathrm{Be}+^{208}\mathrm{Pb}$ and $^{6}\mathrm{He}+^{209}\mathrm{Bi}$ at energies around the Coulomb barrier. It is the first time that we observed two distinct sensitive regions, corresponding to the inner volume absorption and the outer surface absorption processes. Strong energy dependence of the sensitive regions was found as well. Based on this result, we further investigated the interaction property of $^{9}\mathrm{Be}+^{208}\mathrm{Pb}$ and found that the threshold anomaly was observed in the volume interaction, whereas the abnormal near-threshold behavior was presented in the surface part.
