Vlokh of Ministry of Education and Science of Ukraine popup.description2 Optical polarimetric methodological support for polarimetric singular tomography was developed. Topological defects of optical anisotropy parameters (phase difference and angle of the optical indicatrix rotation) were identified in Li2B4O7 glass sample. Experimentally shown that the spatial regions around topological defects are the areas of three-dimensional strained states. The software for experimental data processing and nonlinear equations solution as well as the distribution of the stress tensor restoring was developed. It was found that optical vortices, induced by topological defects of the optical indicatrix orientation with 1/2 strength, have a single charge. The sign of their topological charge is determined by the sign of the spin angular momentum of the incident circularly polarized light, and not by the sign of the strength of topological defect of the optical indicatrix orientation. It is shown that the topological charge of optical vortices in the topological reactions was not saved.
