Holographic Sampling and Holographic Display of Three-Dimensional Space Information Based on Random Fields

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. © 2020, Chinese Institute of Electronics.
