对具有任意相干态的近轴场，利用相干模分解导出了强度输运方程和谱输运方程。我们给出一个简单的例子来说明部分相干和完全相干的强度或光谱传输之间的区别。这里提出的结果可用于估计在各种相对比成像模式的强度响应，并可能形成改进的相位检索技术的基础。
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.
