Abstract

A brief review of the results obtained by the original homodyne technique, using the polarization interferometer and photon correlation spectroscopy for quasi-elastic light scattering in the direction of the incidence of highly coherent laser radiation in liquid crystals (LC), is presented. The surface effects as well as the external field (laser or quasi-static electromagnetic) effects determine the critical behavior of the organic molecular system in the range of temperature phase transitions. The multiplicative nature of the molecular fluctuations in this system under external field leads to nonlinear scattering and a noise-induced phase transition occurs.
