Abstract
- A secure holographic memory system is proposed by use of an encoded reference beam. The reference beam is encrypted by a fiber-optic faceplate, which serves as a phase mask. There are seven keys in the system including the position and direction of the fiber bundle and the direction of the incident beam. The experiment shows that the total key length is larger than 1.8 x [10.sup.19]. The method can be used directly in a shift-multiplexing system with high selectivity. OCIS codes: 210.0210, 210.2860, 070.4560, 190.5330.
