Holographic three-dimensional display is an important display technique because it can provide all depth information of a real or virtual scene without any special eyewear. In recent years, with the development of computer and optoelectronic technology, computer-generated holograms have attracted extensive attention and developed as the most promising method to realize holographic display. However, some bottlenecks still restrict the development of computer-generated holograms, such as heavy computation burden, low image quality, and the complicated system of color holographic display. To overcome these problems, numerous algorithms have been investigated with the aim of color dynamic holographic three-dimensional display. In this review, we will explain the essence of various computer-generated hologram algorithms and provide some insights for future research.

“…HOEs can, in principle, be structured into 2D or 3D lattices, and in the 2000s, HOEs were extended to 2D or 3D lattices with the rise of PDLC technology. [ 57–60 ] However, despite similarities in working principle and structural dimensions, their main applications, such as holographic data storage, [ 49,87–97 ] holographic lens, [ 64,66,69,74–79,82 ] and AR/VR technologies, [ 64–85,291–293 ] are different from those of PhCs (e.g., nanolasers, waveguides, colorimetric sensors, and display pixels). These aspects further prevented HOEs from being viewed as PhCs.…”

“…This has led to the development of both holographic materials (e.g., intensity/polarization holographic materials such as diffractive [ 4–19 ] and holographic optical elements [ 20–60 ] (DOEs and HOEs)) and recording and reconstruction strategies (e.g., Gabor‐, [ 2,3 ] Denisyuk‐, [ 61 ] and Leith/Upatnieks [ 62,63 ] ‐type holograms). These research efforts had progressed and matured well from the 1960s to the 1990s, and many applications of Fourier optics such as augmented reality/virtual reality (AR/VR), [ 64–86 ] 3D optical data storage, [ 49,87–97 ] and Bragg diffractive visual sensors, [ 98–102 ] benefitted significantly from such impressive developments in holographic technologies.…”

Since the 1990s, applications of holography and Fourier optics have been significantly expanded from the spatial modulation of light propagation to the nanofabrication of superlattices. Holographic mixing of multiple beams is found to be highly compatible with unprecedented engineering of 1D, 2D, and 3D superlattices, particularly at the nanoscales. This is essential for the development of champion photonic crystals working at optical frequencies. However, these extensive efforts toward holographic photonic crystals have declined with the failure to obtain a champion photonic crystal and the rapid rise of other important classes of optical modes in the 2010s such as Weyl points, bound state in continuum (BIC), and exceptional points (EPs). To obtain photonic crystals, the symmetric modulations of the sinusoidally distributed real part of permittivity (Re(ε)), that can be considered as waves of matter from the viewpoint of Fourier optics, are sufficient. However, Weyl points, BIC, and EPs demand more complicated and advanced modulation of such as asymmetrically distributed wave of Re(ε) and the coupled Re(ε) and imaginary ε (Im(ε)). It is, therefore, important to determine whether holographic fabrications can be an efficient solution to Weyl points, BIC, and EPs. In this review, a comprehensive overview of holography, Fourier optical surface/volume gratings, and their implementations for Weyl points, BIC, and EPs is presented.

Phase-only holograms are more attractive than the amplitude holograms for the higher energy utilization and the possibility to realize on-axis holographic 3D display without conjugate image. In this study, we propose a high-resolution phase-only holographic 3D display using the light field images rendered in the frequency domain. The high-resolution phase-only hologram contains a large number of elemental phase-only holograms (EPHs), and each EPH is calculated from the light field image of the corresponding viewing point in frequency domain through weighted GS (Gerchberg-Saxton) algorithm. Parallel calculation is performed to speed up the calculation in the row direction and the previous EPH is used as the initial phase for the current EPH calculation in order to improve the display quality due to the great similarity between adjacent light field images. Two high-resolution phase-only holograms both with the size of 64 mm×64 mm and the resolution of 200k×200k pixels were calculated and printed by our homemade holographic printer. The full-parallax and high quality 3D displays were verified by optical experiments, which have the potential to be applied in holographic advertising and other fields.
