　　对数字全息图进行光电再现时，受显示器件分辨率的限制，仅部分数字全息图可以得到有效再现。再现时受直透光影响，所接收的图像通常较为黯淡。在此利用菲涅耳数字全息图的冗余性较高的特点，通过保留原部分再现像的振幅以恢复物光的相位，利用二元全息干涉原理生成新的数字全息图提高衍射效率，并利用数字微镜器件（DMD）作为再现器件重构高质量再现像。

Only a part of the digital hologram can be effectively reproduced in photoelectric reproduction of the digital holo-gram,because of the restriction of the display device resolution. Affected by the zero-order light,the reproduced image received is usually bleak. In this paper,according to the Fresnel digital hologram’s features of high redundancy,the phase of the object light can recovered by retaining the original amplitude in part of the reconstructed image,a new digital hologram can be gener-ated to improve the diffraction efficiency by using the principle of binary holographic interference,and then a high-quality recon-structed image can be reconstructed by taking a digital micromirror device(DMD)as a reconstructive device.
