3D polarization algorithms for processing digital microscopic images of polygraphic polymers
(ВПІ КПІ ім. Ігоря Сікорського, 2022) Ushenko, O.; Horskyi, M.; Soltys, I.; Dubolazov, O.
A method of azimuthally invariant 3D Mueller-matrix mapping of the distributions of the parameters of phase and amplitudeanisotropy of partially depolarizing layers of high-quality (group1 — high density) and low-quality (group 2 — low density) poly-ethylene polymer films has been proposed and substantiated.Layer-by-layer coordinate distributions of the magnitude of theset of Mueller-matrix invariants (MMI) of polymer films of bothtypes were obtained in the volume of polymer samples.

Multilevel digital algorithms for statistical analysisof microscopic images for differentiating temperature changes in polygraphic polymers
(ВПІ КПІ ім. Ігоря Сікорського, 2022) Dubolazov, O.; Soltys, I.; Horskyi, M.; Matymish, M.
This work is aimed at generalizing the methods of laserpolarimetry to the case of partially depolarizing opticallyanisotropic polymer layers. Mueller’s differential matrix map-ping method was proposed and substantiated for reproducingthe distributions of the parameters of linear and circular bire-fringence and dichroism of methyl acrylate layers under different temperature conditions (200 — group 1) and (450 — group 2).
