TLDR
In this article, the polarization properties of an optical fiber are deduced from the backscattered light using polarization-optical time-domain reflectometry, and the results of measurements on a fiber showing both linear and circular retardation are compared with a theoretical model.Abstract:
The technique of polarization-optical time-domain reflectometry is analyzed to see how the polarization properties of an optical fiber may be deduced from the backscattered light. It is shown that, subject to certain assumptions, the polarization is modified as it would be by a linear retarder. The results of measurements on a fiber showing both linear and circular retardation are given and compared with a theoretical model. The experiments show that the accuracy of measurement is limited by changes in the polarization, due to the scattering process, which vary randomly along the fiber.read more

A New Calculus for the Treatment of Optical SystemsI. Description and Discussion of the Calculus
TL;DR: In this paper, the effect of a plate of anisotropic material such as a crystal on a collimated beam of polarized light may always be represented mathematically as a linear transformation of the components of the electric vector of the light.

TL;DR: In this article, the general theory developed in Part I and the derivation of the matrices representing two optical elements which were not treated in Parts II and III are discussed. But the discussion is limited to monoclinic and triclinic crystals which do not possess optical activity.

TL;DR: In this paper, it was shown that any optical system which contains only retardation plates and rotators is optically equivalent to a system containing only two plates, one a retardation plate, and the other a rotator.
