We present a high-resolution three-dimensional (3D) holographic display using a set of elemental images obtained by passive sensing integral imaging (II). Hologram calculations using a high-density ray-sampling plane are achieved from the elemental images captured by II. In II display, ray sampling by lenslet array and light diffraction limits the achievable resolution. Our approach can improve the resolution since target objects are captured in focus and then light-ray information is interpolated and resampled with higher density on ray-sampling plane located near the object to be converted into the wavefront. Numerical experimental results show that the 3D scene, composed of plural objects at different depths from the display, can be reconstructed with order of magnitude higher resolution by the proposed technique.
我们提出了一种使用通过被动感应积分成像（II）获得的一组基本图像的高分辨率三维（3D）全息显示。通过 II 捕获的基本图像来实现使用高密度光线采样平面的全息图计算。在 II 显示中，透镜阵列的光线采样和光衍射限制了可实现的分辨率。我们的方法可以提高分辨率，因为目标物体被聚焦捕获，然后在靠近要转换的物体的光线采样平面上以更高的密度插值和重采样光线信息，将其转换为波前。数值实验结果表明，通过所提出的技术，可以以更高的分辨率重建由来自显示的不同深度的多个物体组成的 3D 场景。
