On the interconnection between correlation and singular-optics approaches in polarization diagnostics of fields from biological tissues

The correlation between the topological and the statistical approaches to describe inhomogeneously polarized optical fields is considered. Two main models describing coordinate distributions of polarization parameters within the topological approach, viz. the "island" model and the "toy-in-toy" one are experimentally proven. It is shown that the correlation length of polarization parameters of the field is comparable with the mean distance between points with orthogonal states of polarization.
