Abstract
We report a speckle-based hologram multiplexing recording technique, in which a multimode LiNbO3 single crystal fiber is employed to generate speckle patterns of reference beams in hologram recording process. By applying an external E-field, the speckle pattern generation and reconstruction can be precisely controlled. A theoretical analysis and a numerical simulation of speckle pattern generation have been conducted. According to the simulation results, this technique can generate thousands of decorrelated reference beams at given practical constraints. The storage capacity can be scaled up as material properties are improved, making this technique well adapted to new material development.
