    "abstract": "An example of a coherent measurement for the direct evaluation of the degree\nof polarization of a single-mode optical beam is presented. It is applied to\nthe case of great practical importance where depolarization is caused by\npolarization mode dispersion. It is demonstrated that coherent measurement has\nthe potential of significantly increasing the information gain, compared to\nstandard incoherent measurements.",
