A simple method of measuring the electro-optic coefficients of polymer films has been reported. In this method, the inverse piezoelectric effect of quartz crystal is used to compensate the optical path change caused by the electro-optic effect of the polymer film. The method of measuring the electro-optical coefficient of the polymer film relative to the piezoelectric constant d1 1 of the quartz crystal can be used to measure all Optical film electro-optic coefficient. The article describes the use of this method to measure the electro-optic coefficient of several new polymer films
