    "abstract": "We demonstrate a coherent quantum measurement for the determination of the\ndegree of polarization (DOP). This method allows to measure the DOP in the\npresence of fast polarization state fluctuations, difficult to achieve with the\ntypically used polarimetric technique. A good precision of the DOP measurements\nis obtained using 8 type II nonlinear crystals assembled for spatial walk-off\ncompensation.",
