Abstract The holographic diffuser plays a significant role in the reconstruction performance of the large-size integral imaging display system. However, the influence of the holographic diffuser on the display quality is seldom theoretically analyzed. In this paper, a quantitative beam analysis approach is proposed, and a diffusing model is established to analyses the influence of the position and diffusing-angle of the holographic diffuser on different reconstruction points, then the mechanism of the aliasing effect caused by the holographic diffuser is revealed. Both the numerical and optical experiments are implemented to prove the validity of the established model, and the results are well agreed with the theoretical analysis, which shows that when the holographic diffuser with a certain diffusing-angle is located at the far-end of the marginal depth plane instead of the traditional central depth plane (CDP), the system can obtain an enhanced aliasing-free depth of field and have a better viewing effect, which is inconsistent with the traditional intuition and experience.

整体成像显示系统中全息漫射器的特性：一种定量光束分析方法

摘要 全息漫射体对大尺寸整体成像显示系统的重建性能起着重要作用。然而，很少从理论上分析全息漫射器对显示质量的影响。本文提出了一种光束定量分析方法，建立了漫射模型，分析了全息漫射器的位置和漫射角对不同重构点的影响，进而分析了全息漫射器引起混叠效应的机理。被揭露。通过数值实验和光学实验验证了所建立模型的有效性，结果与理论分析吻合较好，
