Abstract
An example of a coherent measurement for the direct evaluation of the degre e of polarization of a single-mode optical beam is presented. It is applied to the case of great practical importance where depolarization is caused b y polarization mode dispersion. It is demonstrated that coherent measuremen t has the potential of significantly increasing the information gain, compa red to standard incoherent measurements.
