Paper Abstract

In spatial multiplexing method, the steering devices for reference wave and object wave are necessary. A new scheme applying computer-generated holograms(CGHs) to the steering device is proposed. The beam steering device using CGHs can be performed simultaneously the coarse address function directing the reading or writing beams to the suitable layer and the fine address function corresponding to the particular holographic page within the chosen common volume unit. This new scheme is compared with both the beam steering method using spatial/angular multiplex AODs and the mechanically steered method in terms of access time, cost, and efficiency.
