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.

“…Furthermore, phase modulation has several advantages over amplitude modulation, most notably a much higher diffraction efficiency [12]. As a result, a significant portion of the current research in CGH has been focused on generating POHs [13][14][15][16]. This has led to the development of a wide range of techniques for generating POHs that are specifically tailored to different types of scenes and applications.…”

In this work, we implement a fast non-iterative method for the generation of binary amplitude Fresnel holograms and demonstrate their application in a holographic projection scheme based on a digital micromirror device. To achieve this, we perform the binarization of phase-only holograms generated using an optimized Fresnel random phase. We analyze the quality of the resulting binary amplitude holograms and compare them with holograms obtained with the conventional iterative Fresnel algorithm as a function of the number of iterations and the propagation distance. Additionally, we evaluate the diffraction efficiency in both methods. We demonstrate that the holograms produced with our proposal present significantly advantages in computation speed without a significant reduction in the reconstruction quality. Both experimental and numerical results confirm the effectiveness of our proposal.

“…The holographic display can reconstruct complete wave front including the phase and amplitude and is the most ideal 3D display [1][2][3]. The color rainbow hologram is a special kind of hologram, which can be reproduced with white light illumination by controlling the dispersion in one direction and provide the field of view (FOV) in the orthogonal direction [4][5][6][7][8][9][10]. The color rainbow hologram can be made by optical exposure [4,5] or calculated by computer [6][7][8][9][10].…”

In this research, a fast method to calculate the color rainbow holographic stereogram by taking full advantage of the sparsity of the frequency domain is demonstrated. The color rainbow holographic stereogram (CRHS) is a novel color rainbow hologram containing a large number of elemental CRHSs, where each elemental CRHS only reproduces the color light field information of local 3D color object. The color of the reconstructed color 3D image perceived by the human eye is determined by the spectrum of the reproduced dispersion of different elemental CRHSs that enter the human eye. The calculation of the CRHS is implemented with parallel computing by inversely Fourier transforming the frequency of each elemental CRHS. With the proposed method, the computation time for a resolution of 200k × 200k pixels and size of 64mm × 64mm CRHS is only 15.4 min for a color 3D model with 406k object points. The optical reconstruction with a white LED light illumination proves the effectiveness of our proposed method, which can be applied to the field of color holographic 3D display, advertising or holographic packaging.
