Paper Abstract

We present a simple technique for hologram multiplexing to handle images imposed on different polarization states simultaneously, where light of randomly distorted wavefront and randomly disarrayed polarization is deliberately exploited as a reference light. Such randomly blurred light is generated in succession by a rotary movement of a bundle of optical multi-mode fibers. We show that the direct use of light passing through the fiber bundle contributes to improve the storage capacity of previous hologram recording systems in which a polarizer has been employed with a fiber bundle in rotary movement. Since the actual wavefront patterns provided by fiber bundles are not completely random but quasi-random, a theoretical investigation on the performance of hologram multiplexing is carried out with numerically created quasi-random patterns prior to an experiment. In the end, we perform the experiment of hologram multiplexing for the validity of our approach.
