提出了一种新的数字合成全息图消隐算法。该算法能够处理全视差全息图，并能去除三维(3-D)表面物体发出的物波中的障碍场。该算法首先讨论了利用波场的旋转变换得到倾斜平面后面的场的严格过程，最后得到了减少计算时间的轮廓近似。给出了用该算法生成的全息图的再现结果。
A novel algorithm is presented for hidden-surface removal in digitally synthetic holograms. The algorithm is able to work with full-parallax holograms and remove obstructed fields in the object wave emitted from threedimensional (3-D) surface objects. This algorithm is initially discussed as a rigorous procedure to obtain fields behind a tilted planar surface by using the rotational transformation of wave fields, and finally results in the silhouette approximation for reduction of computation time. Reconstructions of holograms created by using the algorithm are demonstrated.
