Measurements of three dimensional electric field distribution in dielectric liquids

Electric field maps in three dimensions have been able to be drawn using Kerr electro-optic effect and CT (computer tomography) methods. Two-dimensional electric vectors and vector distributions have also be measured successfully by many workers. Extending this method, the authors have developed the method in which three dimensional vector components have been determined by input to output ratios along two orthogonal directions. In this case, the three dimensional Kerr effect should be formalized from the conventional Kerr effect equation
