Paper Abstract

A novel method of measuring the two-dimensional electrostatic field is presented. Based on the dual transverse Pockels effect in some crystals, the electro- optic phase retardation and the azimuth angle of the principal axis in this type of crystal are separately controlled by the applied electric field magnitude and its direction. Therefore, the magnitude and direction of the unknown electric field can be determined by measuring the phase retardation and the azimuth angle. Within the range of 50 kV/m, the experiment on measuring the two-dimensional electrostatic field by using a z-propagating LiNbO3 crystal shows that the nonlinearity errors are less than 4.5% for the field magnitude measurement, and less than 2.3% for its direction. This method will probably be applied to the spot measurement on the two-dimensional electrostatic field.
