    "abstract": "A measure of the degree of polarization for the three-dimensional\npolarization matrix (coherence matrix) of an electromagnetic field is proposed,\nbased on Rayleigh scattering. The degree of polarization, due to dipole\nscattering of the three-dimensional state of polarization, is averaged over all\nscattering directions. This gives a well-defined purity measure, which, unlike\nother proposed measures of the three-dimensional degree of polarization, is not\na unitary invariant of the matrix. This is demonstrated and discussed for\nseveral examples, including a partially polarized transverse beam.",
