Abstract: A simple interferometric method for measuring the linear electro-optic coefficients of poled polymer films is described．This is based on compensating the optical path length due to the electro-optic effect of the poled polymer film by the aanti-piezoelectric effect of a quartz crystal．The value of the linear electro-optic coefficients of the poled polymer films relative to the piezoelectric constant all of a quartz crystal have been measured．This method can be used for measuring the linear electro-optic coefficients of all optical thin films．The linear electro-optic coefficients of several new poled polymer thin polymer films have been determined by using this method．
