| 摘 要： | 虽然真彩色实时全息显示技术在近几年已经取得了阶段性的发展，如何实现符合人眼视觉条件的理想三维显示是一项具有很有挑战性的工作.本文提出了基于随机场的局部平均采样理论，并借助光子波函数的四维傅里叶变换，搭建了以体像素和空间谱为基本抽样单位的三维空间信息的全息抽样框架，并进一步通过实例将这一新的数学模型成功应用于三维空间信息的离散采样、完整恢复与全息显示.最后借助商用4K平面显示器，结合小透镜阵列和全息功能屏，成功演示了人眼可分辨的典型完美全息三维场.

| Abstract: | Although real-time holographic display technology has been developed in recent years,how to develop an ideal 3D(three dimension) display that meets human visual condition is always a challenging task.Based on the four-dimensional Fourier transforms of the wave function of photons,a holographic sampling theory is proposed for the information of a three-dimensional space with the sampling unit by hoxel and spectrum (spatial spectrum).It is successfully applied to the practice of three dimensional information processing such as discrete acquisition,integral restoration and holographic display of a three dimensional space.Based on a commercial 4K flat-panel displayer and the microlens arrays combined with a holographic functional screen,the perfect holographic three-dimensional displays for human vision is demonstrated. |
