论文摘要
我们提供了超分辨率成像技术的定量分析，该技术利用了来源的光度的时间波动，以击败瑞利极限。我们定义了功绩合理的分辨率增益数字，这使我们能够将估计理论概念与成像群落中通常使用的概念联系起来，并得出基本的分辨率限制，最多可以扩展为源均值的第四根线。我们考虑了有限的光子数量和采样时间的影响，我们将微调和基准的最先进方法的性能（以共同的首字母缩写为SOFI），重点介绍了基于累积的图像处理技术（以公共首字母缩写为SOFI）。
We provide a quantitative analysis of super-resolution imaging techniques which exploit temporal fluctuations of luminosity of the sources in order to beat the Rayleigh limit. We define an operationally justified resolution gain figure of merit, that allows us to connect the estimation theory concepts with the ones typically used in the imaging community, and derive fundamental resolution limits that scale at most as the fourth-root of the mean luminosity of the sources. We fine-tune and benchmark the performance of state-of-the-art methods, focusing on the cumulant-based image processing techniques (known under the common acronym SOFI), taking into account the impact of limited photon number and sampling time.
