摘要

我们描述了相干和非相干效应在由相干源照射的无序介质中发生的情况。我们通过考虑标量波在点、各向同性散射体介质中的传播来说明从相干到非相干的转变。我们注意到传统输运方程是如何演变的，并且它被一个边界层所丰富，在这个边界层中相干性衰减并且强度具有阻尼振荡性质。

Radiative Transport Reconsidered

We describe situations where coherent and incoherent effects take place in a disordered medium illuminated by a coherent source. We illustrate the transition from coherence to incoherence by considering the propagation of a scalar wave in a medium of point, isotropic scatterers. We note how a traditional transport equation evolves and that it is enriched by a boundary layer in which coherence decays and the intensity is of damped oscillatory nature.
