在本文中，我们提出了一种使用附加大口径透镜的曲面积分成像系统。额外的大光圈镜头提供了全方位的曲率效果，与传统系统相比，提高了视角。所提出的系统结构简单，因为使用了精心制作的传统平面器件，无需任何修改。介绍了一种改进的基于ABCD矩阵的计算机生成拾取技术来计算所提出系统的元素图像。为了证明该系统的有效性，进行了光学实验，并给出了实验结果。此外，根据目标位置和图像尺寸的限制，从理论上分析了增强视角。
In this paper, we propose a curved integral imaging system using an additional large-aperture lens. The additional largeaperture lens provides full-directional curvature effect and improves viewing angle compared with conventional system. The proposed system has a simple structure due to the use of well-fabricated conventional flat devices without any modification. A modified computer-generated pickup technique based on ABCD matrix is introduced to calculate elemental images of the proposed system. To show the usefulness of the proposed system, optical experiments are carried out and the results are presented. In addition, we analyze the enhanced viewing angle according to the object location and the limited image size theoretically.
