Paper Abstract

In this paper, a new speckle based hologram multiplexing recording technique is proposed and tested. In this method, a multi-mode LiNbO3 single crystal fiber is employed to generate speckle patterns which are used as reference beams in hologram recording process. The speckle pattern generation can be precisely controlled by external E-field. Theoretically, this technique can generate thousands of decorrelated reference beams at given practical constraints. Its storage capacity can be scaled up as material properties are improved, making it well adapted to new material development. A theoretical analysis and numerical simulation of speckle pattern generation are also presented in this paper.
