Review of computer-generated hologram algorithms for color dynamic holographic three-dimensional display

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.
