Plenoptic imaging systems are often used for applications like refocusing, multimodal imaging, and multiview imaging. However, their resolution is limited to the number of lenslets. In this paper we investigate paraxial, incoherent, plenoptic image formation, and develop a method to recover some of the resolution for the case of a two-dimensional (2D) in-focus object. This enables the recovery of a conventional-resolution, 2D image from the data captured in a plenoptic system. We show simulation results for a plenoptic system with a known response and Gaussian sensor noise.
全光成像系统常用于诸如重新聚焦、多模态成像和多视图成像等应用。然而，它们的分辨率受限于微透镜的数量。在本文中，我们研究傍轴、非相干全光图像形成，并针对二维（2D）对焦物体的情况开发一种恢复部分分辨率的方法。这使得能够从全光系统中捕获的数据恢复传统分辨率的2D图像。我们展示了具有已知响应和高斯传感器噪声的全光系统的仿真结果。
