Paper Abstract

The direction of liquid crystal (LC) arrangement can be changed by different techniques. Photo-alignment method appears to be potentially the best technique to use in the case of micro–capillaries. Developing the photo-alignment method of liquid crystal molecules in silica micro–capillaries allowed to work on obtaining periodic orientation. The usage of amplitude masks in the irradiation allows to obtain a periodic alignment of molecules variable within a single sample. In this paper, the experimental results of the periodic orientations achieved are presented.
