摘要
为了进一步研究计算全息3维显示的方法，以数字微镜器件为空间光调制器，采用层析法，结合菲涅耳衍射积分算法中的角谱法，探讨了全息图的计算与数字微镜器件参量之间的关系，并利用修正立轴参考光编码的方式，得到了菲涅耳计算全息图。通过对计算全息图进行数值模拟及实验验证，均得到了较好的再现像。结果表明，该方法实现了3维物体的再现，为计算全息3维显示提供了一种有效的方法。
Abstract
In order to achieve high-quality hologram reconstruction based on digital micro-mirror device (DMD), gray scale adjustment characteristics and Fresnel diffraction characteristics of DMDs were described in detail. Then, the principle of holographic display based on DMD was analyzed. Finally, high-quality hologram was reconstructed. The results demonstrate holographic display was improved obviously after grayscale-adjustment. The results are helpful for the display of computer generated hologram based on digital micro-mirror device.
