Voltage controlled light transmittance in polymer dispersed liquid crystals

In recent papers we have studied the optical phase shift induced by a Polymer Dispersed Liquid Crystal (PDLC) sample subjected to a low frequency electric field. In the framework of the droplet model for the PDLC we have shown that the description of the sample by means of three (molecular, droplet and sample) order parameters and two (a surface elastic constant and a characteristic voltage constant) sample related parameters is able to give a good agreement with experimental data. In this paper we present further ap plications of the model showing how applied voltages controls light scattering.
