论文摘要
相关元素成像（CPI）是一种无扫描衍射限制的3D光学成像技术，利用相关光源的特性特性。 CPI已被进一步扩展到在称为相关灯场显微镜（CLM）的修改结构中，将CPI扩展到显微镜（例如荧光或散射对象）的样本。有趣的是，实验表明，与原始CPI方案相比，CLM的噪声性能显着改善，从而导致更好的图像和更快的获取。在这项工作中，我们通过研究CLM和原始CPI设置的信噪比和信噪比的比率，为这种优势提供理论基础。
Correlation plenoptic imaging (CPI) is a scanning-free diffraction-limited 3D optical imaging technique exploiting the peculiar properties of correlated light sources. CPI has been further extended to samples of interest to microscopy, such as fluorescent or scattering objects, in a modified architecture named correlation light-field microscopy (CLM). Interestingly, experiments have shown that the noise performances of CLM are significantly improved over the original CPI scheme, leading to better images and faster acquisition. In this work, we provide a theoretical foundation to such advantage by investigating the properties of both the signal-to-noise and the signal-to-background ratios of CLM and the original CPI setup.
