An innovative approach is proposed for calculating high resolution computer generated integral holograms by using the Fourier Ptychographic (FP) algorithm. The approach initializes a high resolution complex hologram with a random guess, and then stitches together low resolution multi-view images, synthesized from the elemental images captured by integral imaging (II), to recover the high resolution hologram through an iterative retrieval with FP constrains. This paper begins with an analysis of the principle of hologram synthesis from multi-projections, followed by an accurate determination of the constrains required in the Fourier ptychographic integral-holography (FPIH). Next, the procedure of the approach is described in detail. Finally, optical reconstructions are performed and the results are demonstrated. Theoretical analysis and experiments show that our proposed approach can reconstruct 3D scenes with high resolution.
提出了一种创新方法，用于通过使用傅里叶叠层成像（FP）算法来计算高分辨率计算机生成的积分全息图。该方法用随机猜测初始化高分辨率复全息图，然后将由积分成像（II）捕获的元素图像合成的低分辨率多视图图像拼接在一起，通过具有FP约束的迭代检索来恢复高分辨率全息图。本文首先分析了多投影全息图合成的原理，接着精确确定了傅里叶叠层成像积分全息术（FPIH）所需的约束条件。接下来，详细描述了该方法的过程。最后，进行了光学重建并展示了结果。理论分析和实验表明，我们提出的方法可以重建高分辨率的三维场景。
