    A spatial light modulator applied to the collinear volume holographic storage system uses a hollow phase modulator to modulate the surrounding portion of an incident light to be a reference light, and the center portion of the incident light is modulated by an amplitude modulator to be a signal light. Thus, the spatial light modulator can enhance the convergence of the point spread function of the system.
