In this work, we discuss the interest of using the indices of polarimetric purity (IPPs) as a criterion for the characterization and classification of depolarizing samples. We prove how differences in the depolarizing capability of samples, not seen by the commonly used depolarization index P, are identified by the IPPs. The above-stated result is analyzed from a theoretical point of view and experimentally verified through a set of polarimetric measurements. We show how the approach presented here can be useful in easily synthetizing depolarizing samples with controlled depolarizing features, just by properly combining low-cost fully polarizing elements (such as linear retarders or polarizers).
在这项工作中，我们讨论了使用极化纯度指数（IPP）作为去极化样本表征和分类标准的意义。我们证明了，常用的去极化指数P无法体现的样本去极化能力差异，可通过IPP识别出来。从理论角度分析了上述结果，并通过一组极化测量进行了实验验证。我们展示了，仅通过适当地组合低成本的全极化元件（如线性延迟器或偏振器），这里提出的方法如何能用于轻松合成具有可控去极化特性的去极化样本。
