A single‐panel complex holographic display with a three‐phase covalent macropixel featuring ultralow noise and high‐efficiency 3D image generation is proposed. The essential feature of the proposed three‐phase covalent macropixel is the point‐symmetric covalent concatenation of sub‐pixels and an adaptive computer‐generated hologram encoding algorithm. The proposed single‐panel holographic display exhibits three times signal efficiency enhancement, 1/38 reduction of DC noise, and 1/50 reduction of conjugate noise compared to conventional holographic displays in the generation of full‐color computer‐generated hologram images. This noise reduction leads to three times the optical efficiency enhancement of holographic displays.

具有三相共价宏像素的单面板复杂全息显示

提出了一种具有三相共价宏像素的单面板复杂全息显示器，具有超低噪声和高效的 3D 图像生成功能。所提出的三相共价宏像素的基本特征是子像素的点对称共价串联和自适应计算机生成的全息图编码算法。与传统全息显示器相比，在生成全彩计算机生成的全息图像时，所提出的单面板全息显示器的信号效率提高了三倍，直流噪声降低了 1/38，共轭噪声降低了 1/50。这种噪声降低使全息显示器的光学效率提高了三倍。
