提出一种将数字全息术和传统光学全息结合的方法制作动态全息图。首先通过三维扫描仪获得实际三维物体不间姿态的物光分布数据,然后利用计算机全息技术获得高质量的二步彩虹中的主全息图H1,最后再用光学的方法得到彩虹全息图。该技术充分利用了计算全息技术的灵活性,同时解决了视角和白光再现的问题,获得了较好的实验结果。
A new approach is presented which combines the computer-generated holography and the synthetic technique for dynamic rainbow holography. Firstly, the object beam distribution data of the practical object are acquired by using 3-D scanner; Secondly, the computer-generated holography is applied to make the main hologram H1 with good quality. Lastly,the traditional method is used to reconstruct the dynamic image. This approach takes the advantage of the computer-generated holography and simultaneously deals with the problem of large viewing angle and reconstruction in white light. Finally,we obtain the elementary experiment result.
