Space averaged polarization characteristics of inhomogeneous vector field

Interrelation of the fine structure of the vector field and its averaged polarization characteristics is considered. It is shown that space averaged Stokes parameters are defined by dispersion of the phase difference in its saddle points. The dispersion of phase difference and dimension of areas with considerable polarization changes are defied by the averaged space between the nearest adjacent component vortices of the same sign. The results of computer simulation and experimental investigation are presented. Good correlation between these results is observed.
