Paper Abstract

Firstly, this paper introduces the concept of multi-level digital holographic storage. Then, application of digital image processing technology is brought forward in the data restoring process of digital holographic storage. Information in the reconstructed digital images collected from CCD camera is enhanced through digital image processing technology and threshold decision is gone on so as to decreasing bit error ratio of system. Based on above-mentioned ideal, the programming project is designed, which is applicable to binary and multi-level digital holographic storage. Finally, the quality of a binary experimental image is improved through digital image processing program and the accuracy of threshold decision can be improved.
