论文摘要
在过去的十年中，解释部分连贯性的无透镜成像方法已经变得非常普遍。但是，尽管使用此类指标可以比较完全相干的对象和波场，但没有使用指标来比较部分相干的光场。在这里，我们展示了如何从量子状态保真度上重新划出平方误差和傅立叶环相关性，自然而然地将它们推广到部分连贯的波场。这些结果填补了无透镜成像文献中的重要空白，并将能够对重建的部分相干波场的可靠性和分辨率进行定量评估。
Lensless imaging methods that account for partial coherence have become very common in the past decade. However, there are no metrics in use for comparing partially coherent light fields, despite the widespread use of such metrics to compare fully coherent objects and wavefields. Here, we show how reformulating the mean squared error and Fourier ring correlation in terms of quantum state fidelity naturally generalizes them to partially coherent wavefields. These results fill an important gap in the lensless imaging literature and will enable quantitative assessments of the reliability and resolution of reconstructed partially coherent wavefields.
