论文摘要
通过将高维的光视野成像信息编码到可检测的二维斑点平面中，通过稀疏限制（GISC摄像机），幽灵成像摄像头可以直接使用一个快照，直接捕获高维灯场成像信息。这使得值得重新审视此光学成像系统的空间分辨率极限。在本文中，我们在理论和实验上都表明，尽管高维光场空间的分辨率仍然受衍射的限制，但与古典雷利的标准相比，GISC摄像机的统计空间分辨率可以大大改善，通过利用高维光领域的可见度。还展示了成像分辨率，光场自由度和在高维光场空间中物体自由度之间的相互作用。
By encoding the high-dimensional light-field imaging information into a detectable two-dimensional speckle plane, ghost imaging camera via sparsity constraints (GISC camera) can directly catch the high-dimensional light-field imaging information with only one snapshot. This makes it worth to revisit the spatial resolution limit of this optical imaging system. In this paper we show both theoretically and experimentally that, while the resolution in high-dimensional light-field space is still limited by diffraction, the statistical spatial resolution of GISC camera can be greatly improved comparing to classical Rayleigh's criterion by utilizing the discernibility in high-dimensional light-field space. The interaction between imaging resolution, degrees of freedom of light field, and degrees of freedom of objects in high-dimensional light-field space is also demonstrated.
