To investigate the thermo-optical effect in liquid crystal(s) (LC)s the statistical methods of experiment planning are applied. The experiment was conducted in accordance with the technique of orthogonal central compositional planning. In the course of the experiment, physical parameters (scanning velocity, laser beam intensity, LC temperature) have been varied on five levels. The obtained mathematical model describes the dependence of light-scattering texture dimensions in the LC layer on physical parameters of information by thermo-optical registration. Such a model allows us to determine the suitable function model to obtain the preset dimensions of the light-scattering texture in a LC layer.
