全息存储图像重构所达到的分辨率是评价存储器性能的重要指标。本文利用民用CCD和图像处理技术对不同全息图直径和衍射光功率下的重构图像分辨率进行了定量的研究。发现实际存储时采用3mm的全息图直径较为合适，并在此基础上估算了角度复用所能达到的最大存储密度。
The resolution achieved by holographic storage image reconstruction is an important indicator for evaluating memory performance. In this paper, we use CCD and image processing technology to quantitatively study the resolution of reconstructed images under different hologram diameters and diffraction optical powers. Found that the actual storage using 3mm hologram diameter is more appropriate, and on this basis estimated the angle of reuse can achieve the maximum storage density.
