Abstract
Transport-of-intensity and transport-of-spectrum equations are derived using the coherent mode decomposition for paraxial fields having an arbitrary state of coherence. We give a simple example that demonstrates the difference between a partially coherent and a fully coherent transport of intensity or spectrum. The results presented here may be used to estimate the intensity response in a variety of phase-contrast imaging modalities and may form the basis for improved phase-retrieval techniques.
摘要
利用相干模分解，推导出具有任意相干态的傍轴场的强度和光谱传输方程。我们给出了一个简单的例子，说明了部分相干和完全相干的强度或光谱传输之间的区别。这里给出的结果可用于估计各种相衬成像模式中的强度响应，并为改进的相位恢复技术奠定基础。
