Holographic Image Storage

摘要: 本文提出用于全息存储的"散斑随机相移法"将其与"随机相位抽样法"做了比较,所得实验结果与理论一致。当用新型卤化银全息干版和稀释显影处理,可得再现童象的衍射效率为2%,可分辨的线宽为20μm以及可分辨的灰度级为16。

Abstract: In this paper, the speckle random phase shifter method for holographic image storage is presented and compared with random phase sampling method. The experimental results obtained agree well with the theory. By using new type of silver halide holographic plate and development processing of dilute solution, the diffraction efficiency of the reconstructed image of a girl is 2 percent, the resoluble line width is 20 μm and the number of resoluble grey level is 16.
