  • Photoinduced ordering in the films of photosensitive materials (polymers, dyes, polymer blends,  and liquid crystals)

-  experimental tool (combination of transmission null ellipsometry and  UV/Vis spectrometry) is proposed to study orientational ordering in anisotropic films in a real 3D space. This tool is applied to study 3D ordering peculiarities in LC layers and films of photosensitive polymers and dyes
