ABSTRACT:
A method to obtain polarization characteristics of an optical transmission medium is disclosed. Sequentially plural different states of polarized light are launched into the optical transmission medium. Intensities of light emerging from the optical transmission medium through combinations of optical elements are measured to obtain Stokes parameters from which Stokes vectors describing the emerging light corresponding to each of the plural sequentially launched states of polarization are obtained; for at least three different launched states of polarization, descriptors are used of these launched states of polarization and the Stokes vectors describing the corresponding emerging light to calculate a Jones matrix which mathematically models the changes that the launched light when described in terms of a Jones vector is subject to when passing through the optical transmission medium; and, the Jones matrix is used to describe the polarization characteristics of the optical transmission medium.
