A z-polarized laser is used to knock off electrons from H $_2^-$ in the vicinity of a hard surface. Theoretical imaging method is used to derive a generalized modulation function for the total photodetachment cross-section, which describes invisible oscillation. It is found that the hard surface strongly affects the detached electron flux as well as total photodetachment cross-section. There exists strong dependence on the distance of H $_{2}^{-}$ from the hard surface and also on the separation of atomic centres of H $_2^-$ . Unlike the detached electron flux, no visible oscillations are noted in the photodetachment cross-section.
