In this paper, we propose a depth-enhanced integral imaging display based on bifocal lens array. The bifocal lens array consists of a small lens array with plano-convex circular lens units and a large lens array with square lens units. The proposed display device generates two central depth planes and stitches two reconstructed 3-D images in depth, which largely improves the depth of field. The experimental results indicate that the proposed structure reconstructed 3-D image with the depth of field as large as 150.8 mm, which is double of conventional integral imaging display.

基于双焦透镜阵列的具有增强景深的整体成像显示器

在本文中，我们提出了一种基于双焦透镜阵列的深度增强积分成像显示器。双焦透镜阵列由一个带有平凸圆形透镜单元的小透镜阵列和一个带有方形透镜单元的大透镜阵列组成。所提出的显示设备生成两个中央深度平面，并在深度上拼接两个重建的 3D 图像，这在很大程度上改善了景深。实验结果表明，所提出的结构重建了景深达150.8 mm的3D图像，是传统整体成像显示器的两倍。
