Abstract: A multiplexing scheme in volume holograms with a spherical reference wave implemented by rotating a mirror is presented. Diffraction angular selectivity of the mirror in the proposed holographic storage system is theoretically and experimentally investigated. The spherical reference waves in the presented multiplexing scheme can be replaced with plane reference waves; however, angular selectivity of the mirror with a plane reference wave is higher than that with a spherical reference wave in the system. Angular selectivity of the mirror using a spherical reference wave in the system can be increased by decreasing the distance between the mirror and the hologram. Unlike spherical reference waves, angular selectivity using a plane reference wave stays the same in this system. Although using spherical reference waves generates a lower angular selectivity, it also offers larger total accessible angular range for reference beams. Accordingly, using spherical reference waves in the proposed system will not sacrifice the storage capacity.
