Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.We investigate the optical transmission of a monochromatic laser beam passingthrough an individual domain of a nematic liquid crystal formed by the polycarbonate surface.The domain has the radial orientation structure with a disclination line on the polymer surface,which gradually transforms to “pseudoplanar” alignment at the coherence distance ξ from thesurface. The dependence of the optical transmittance on an electric field applied to the domainare different at various light polarization directions relative to the disclination lines and, in theabsence of an analyzer, are accompanied by interference oscillations. To explain the resultsobtained, a domain is considered to be a gradient lens with the refractive index variable in theplane perpendicular to the laser beam and the resulting deflecting effect that was collected atthe beam path through the liquid crystal layer
