Abstract

This paper brings forward one concept of holographic storage of multi-level digital data at first. It is that each pixel includes more information than 1 bit, which means that a multi-level digital data image provides more information than a binary digital data image with the same pixels. So, the capacity will be increased with this technology. Furthermore, some aspects of holographic storage of multi-level digital data, such as the multi-level coding, storage characters and the quality of the stored image are debated. Finally, we research this holographic storage technology by experiment.
