我们推导出一个场的强度-强度相关性的表达式，该场是由高斯统计的随机场从具有确定性或随机折射率分布的粒子散射而产生的。我们的结果推广了[Opt. Lett. 35，4000，2010]的情况下，任意相关的入射场。作为具体的例子，我们考虑的情况下，一个单一的平面波和两个部分相关的平面波入射在散射体。
We derive expressions for the intensity-intensity correlations of a field produced on scattering of a random field governed by Gaussian statistics from a particle with a deterministic or a random refractive index distribution. Our results generalize the ones in [Opt. Lett. 35, 4000, 2010] to the case of an arbitrarily correlated incident field. We consider as specific examples the cases of a single plane wave and two partially correlated plane waves incident upon the scatterer.
