摘要：
Verities of applications require the technology that allows storing, retrieving, and processing a large volume of information. Holographic technique offers high-density data storage with parallel access and high throughput. Several methods exist for data multiplexing based on the fundamental principle of volume hologram Bragg selectivity. We recently demonstrated that spatial shift selectivity associated with a random (amplitude-phase) encoding of the reference beam is an alternative method for high-density, high capacity data multiplexing. In this report we show some characteristics of the random encoded reference beam hologram selectivity and discuss the parameters of the recording material that should work optimal for this method.
