摘　　要：文中进行了一种新型三维全息图的制作方法研究,该方法基于计算全息原理,与合成全息相结合,实现激光三维全息图的直写打印制作。首先进行了菲涅耳计算全息图的实验,表明计算全息与合成全息结合的可行性与合理性。然后根据合成全息原理与计算全息原理对三维模型进行采样和图像变换处理,再计算出相应的菲涅耳计算全息图,借助数字全息激光打印系统完成三维全息图的拍摄,在激光下进行光学再现,最后对再现结果进行了分析与讨论。A new method of making three-dimensional hologram by laser direct wrinting system was proposed, which was based on the principle of CGH and combined stereo holography. First, the experiment of fresnel computer generated hologram was conducted and the results demonstrated that it is feasible and rational to combine CGH with stereo holography. Then the three-dimensional model was sampled and the sampled image were processed by the principle of stereo holography and CGH. By digital holographic laser printing system, three-dimensional hologram was produced, which could be opticaly reproducted by laser, and the final results were analyzed and discussed.
