Abstract We present a simple yet effective method to realize holographic three-dimensional (3D) display by optimizing arrangement of holograms. After a 3D object is divided into a set of layers in axial direction, these layers are calculated into corresponding sub-holograms by Fraunhofer diffraction. The hologram uploaded on SLM consists of sub-holograms side-by-side. Both simulations and experiments are carried out to verify the feasibility of the proposed method. The difference between Fresnel diffraction and Fraunhofer diffraction in the proposed method is analyzed. Aiming at the problems exposed in the experiments, reconstructed results are discussed and further improved by optimizing arrangement of sub-holograms. The process of 3D modeling is simple and the computational complexity is accordingly reduced. This method may provide a promising solution in future holographic 3D realization.

基于全息图优化排列的全息三维显示

摘要 我们提出了一种通过优化全息图排列来实现全息三维（3D）显示的简单而有效的方法。将 3D 物体沿轴向分成一组层后，通过夫琅禾费衍射将这些层计算为相应的亚全息图。上传到 SLM 的全息图由并排的亚全息图组成。进行了仿真和实验以验证所提出方法的可行性。分析了所提出方法中菲涅耳衍射和夫琅禾费衍射的区别。针对实验中暴露出的问题，讨论了重构结果，并通过优化亚全息图的排列来进一步改进。3D建模过程简单，计算复杂度相应降低。
