(ВПІ КПІ ім. Ігоря Сікорського, 2022) Felde, Kh.; Soltys, I.; Havryliak, M.; Motrych, A.; Ushenko, Yu.; Dvorzhak, V.; Ohirko, M.; Tymchuk, V.; Semeniuk, V.
This manuscript discusses the development of a singular approach to analyzing polarization-inhomogeneous laser fields in order to improve the manufacturing technology of packaging printing products. The analysis is based on a model approach, which represents polyethylene polymer film networks as a two-component amorphous-crystallite matrix.

Technology of protection and control of printed products using application programs of digital introscopy
(ВПІ КПІ ім. Ігоря Сікорського, 2022) Felde, Kh.; Soltys, I.; Havryliak, M.; Motrych, A.; Ushenko, Yu.; Dvorzhak, V.; Liniuchev, O.
The article presents the basics of the method of correlation spatial-frequency filtering of maps of phase distributions of polyethylene films. Using the method of statistical analysis of the structure of spatial-frequency filtered polarization mapsof polymer films, a set of methods and criteria for diagnosingchanges in the birefringence of packaging materials has beensubstantiated and tested.
