论文摘要
我们提出了一种新的方法，通过在感兴趣的三维场景中测量任意选择的两个参考平面之间的光的二阶相关性，以在衍射极限进行元素成像。我们表明，对于混乱的光和纠缠 - 光子照明，该协议使得可以在后处理中改变聚焦平面，并实现图像分辨率和景深的前所未有的组合。特别是，相对于先前的相关性元素成像协议，以及相对于标准成像的数量级，景深就因子3而更大，而分辨率则保持在衍射极限。该结果导致了基于混沌光的相关性群体成像设备的紧凑设计的发展，以及基于纠缠光子照明的高SNR plenoptic成像设备，从而有助于与商业元素有效竞争相关性群体成像。
We propose a novel method to perform plenoptic imaging at the diffraction limit by measuring second-order correlations of light between two reference planes, arbitrarily chosen, within the tridimensional scene of interest. We show that for both chaotic light and entangled-photon illumination, the protocol enables to change the focused planes, in post-processing, and to achieve an unprecedented combination of image resolution and depth of field. In particular, the depth of field results larger by a factor 3 with respect to previous correlation plenoptic imaging protocols, and by an order of magnitude with respect to standard imaging, while the resolution is kept at the diffraction limit. The results lead the way towards the development of compact designs for correlation plenoptic imaging devices based on chaotic light, as well as high-SNR plenoptic imaging devices based on entangled photon illumination, thus contributing to make correlation plenoptic imaging effectively competitive with commercial plenoptic devices.
