【摘要】 当前全息图计算存在效率低和编码信息丢失的问题。为解决以上问题,提出了一种新的复振幅全息图编码方法。方法将角谱法计算得到的复振幅分布拆解成振幅信息和相位信息,通过多相位编码生成包含全部振幅信息和相位信息的全息图。相比传统GS算法,在相同计算时间下,多相位编码方法全息图重建图像PSNR提高了15.49dB,SSIM提高0.65。方法为提高三维显示中全息图重建图像质量提供了新途径。

【Abstract】 Current hologram computation suffers from low efficiency and loss of encoded information. To address these issues, a novel encoding method for complex amplitude hologram is proposed. The proposed approach decomposes the complex amplitude distribution calculated by the angular spectrum method into amplitude and phase information, then generates a hologram containing complete amplitude and phase information through multi-phase encoding. Compared with the traditional Gerchberg-Saxton(GS) algorithm, under the same computation time, the proposed multi-phase encoding method improves the PSNR of the reconstructed holographic image by 15.49 dB and the SSIM by 0.65. This method provides a new approach for enhancing the quality of holographic reconstructed images for three-dimensional display.
