Measurements of the quality of nematic liquid crystal alignment

In this paper we have investigated the alignment of nematic liquid crystal (NLC) molecules in homogenously oriented liquid crystal cells used for nematicons generation. We propose three different methods based on contrast evaluation, linear diffraction and nematicons generation. We showed that LC cell contrast evaluation is not enough from the perspective of nematicons generation. In order to select the best LC cell, all the proposed methods should be combined. © 2016 Photonics Society of Poland.
