Investigation of formation and interrelations of polarization singular structure and Mueller-matrix images of biological tissues and diagnostics of their cancer changes.

We investigate the processes of laser radiation transformation by biological crystal networks using the singular optics techniques. The obtained results show a distinct correlation between the points of "characteristic" values of coordinate distributions of Mueller matrix (M(ik) = 0, ± 1) elements and polarization singularities (L- and C-points) in laser images of biological crystal networks with the following possibility of Mueller-matrix selection of polarization singularity. The technique of Mueller-matrix singular diagnostics of pathological changes in a woman's reproductive sphere tissue (myometrium) is proposed.
