摘　　要：本文基于计算全息、光电衍射再现及散射成像等技术,研究全息空间三维显示,利用随机相位抑制全息空间三维再现像的散斑噪声,实现高分辨率全息空间三维显示。同时,测试不同厚度的散射介质屏对三维成像的影响,探究全息空间三维显示的亮度变化规律。In this paper,holographic spatial 3D display is studied based on computer generated holography,photoelectric diffraction reconstruction and scattering imaging.The system uses random phase to suppress the speckle noise of holographic spatial 3D reconstruction image,and realizes the high-resolution holographic 3D display.Finally,the influence of different thicknesses of scattering medium screens on 3D imaging was investigated,and the brightness variation of the holographic spatial 3D display was studied.
