It was recently demonstrated theoretically that when the polarimetric properties of a material depend only upon the direction transverse to that of propagation (long coherence length regime), depolarization in transmission evolves quadratically with material thickness. This behavior was observed in several experimental studies. However, some of these studies unlikely satisfy the long coherence length condition under which the theory applies. Here, we demonstrate that abandoning a unidirectional approach to the propagation of light through a medium, i.e., introducing scatter, causes quadratic depolarization to occur in the short coherence length regime.

去极化二次演化的散射机制

最近在理论上证明，当材料的极化特性仅取决于横向于传播方向的方向（长相干长度状态）时，透射中的去极化随材料厚度成二次方发展。在一些实验研究中观察到此行为。但是，其中一些研究不太可能满足该理论适用的长相干长度条件。在这里，我们证明了放弃光通过介质传播的单向方法（即引入散射）会导致在短相干长度范围内发生二次去极化。
