Abstract: A polarization-related characteristic of an optical path is determined from a predetermined function of the mean-square of a plurality of differences between polarization-analyzed optical power parameters corresponding to pairs of wavelengths mutually spaced about a midpoint wavelength by a small optical frequency difference. At least some of the said differences correspond to wavelength pairs measured under conditions where at least one of midpoint wavelength, input state of polarization (I-SOP) or analyzed state of polarization (A-SOP) of a pair is different.

Abstract translation: 光路的极化相关特性是根据对应于中点波长相互间隔的一对波长的偏振分析光功率参数之间的多个差的平均值的预定函数由小的光频差确定的。 所述差异中的至少一些对应于在一对中点波长，输入偏振态（I-SOP）或分析的偏振状态（A-SOP）中的至少一个不同的条件下测量的波长对。
