An Apparatus of increased precision for the Measurement of Electro-Optical parameters of Liquid Crystals

The ferroelectric liquid crystals (FLCs) are demanding high attention now a day, because of their potential applications in many electro-optical devices, particularly in displays. The suitable applications of FLCs in devices are decided by their electro-optical properties like tilt angle, birefringence and spontaneous polarization. In this paper we are presenting a new apparatus for highly accurate measurement of electro-optical parameters of FLCs. The accuracy of the apparatus is the best among the currently available equipments in the market. The accuracy and performance of the apparatus has been confirmed by performing the experiments on standard ferroelectric liquid crystals
