摘要
Abstract
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.关键词
