The problem of recovering the coherence features of a partially coherent quasi-monochromatic scalar optical source, starting solely from intensity measurements on the emitted beam, is addressed in the most general way, under the paraxial approximation. In particular, it is shown that on expanding the beam emitted by the source as a bundle of partially correlated Hermite-Gaussian beams, the correlation coefficients can be recovered, in principle, simply by performing scalar products between transverse intensity distributions and suitably defined functions.
在傍轴近似下，以最一般的方式解决了仅从发射光束的强度测量开始恢复部分相干准单色标量光源相干特性的问题。特别地，结果表明，将源发射的光束展开为一束部分相关的厄米 - 高斯光束时，原则上通过在横向强度分布与适当定义的函数之间进行标量积，就可以恢复相关系数。
