The subject of the graduate qualification work is optical anisotropy.The given work is devoted to the study of optical anisotropy in polymer gradient rod structures with axisymmetric distribution of the refractive index. In the course of the work, the optimal regimes for the synthesis of gradans based on ST-EGDMA-MMA (the content of the initiator in the prepolymer matrix, diffusion temperature, the content of EGDMA in the prepolymer matrix, the degree of conversion of the prepolymer matrix) were identified, providing a distribution of the refractive index close to ideal focusing as for obtaining gradans with low OA, and with high OA.Using the integrated photoelasticity method, the radial distributions of the RS axial component for the BUH-115 hailstone were reconstructed and the distributions of the remaining components and their differences were found from them.The effect of the radial dependence of the optical stress coefficient on the RS distribution is studied for the cases when the stress optical coefficient is assumed to be constant over the gradan cross section or varies depending on the radial coordinate. It was found that the indicated radial dependence of the stress optical coefficient is very significant and must be taken into account when reconstructing the RS.
