Abstract
This paper represents the investigation results of spatial chaotization of optical field scattered by liquid crystals during phase transition liquid – liquid crystal under electric field. Two stochastic parameters of the field, namely, Lyapunov's maximal index and correlation exponent was chosen for this study. It has been established that maximum variances of phase inhomogeneities of the nematic liquid crystal corresponds to maximum fluctuations of order parameter under temperature of phase transition liquid – liquid crystal. Was found that analysis of the radiation field scattered during the phase transition process the liquid-liquid crystal allows to accurately determine the phase transition temperature and voltage of forming Williams’s domains.
