Abstract :
We have investigated nonuniform electric field vector distributions in liquid dielectrics. We have already reported on measurements of symmetrical and nonsymmetrical electric field vector distribution using Kerr electrooptic effect and our unique reconstruction method modified computed tomography technique. The measurement system was composed of a He-Ne laser, a polarizer, a quarter-wave plate, an experimental cell, an analyzer, and a photo-detector. For the measurement of a field vector distribution, it was necessary to measure light intensity twice with changing the optical axis of optical wedges. Moreover, the intensity measurement must be carried out at many points from θ=0 to π around the electrode system. Therefore it took considerable time to measure an electric field distribution. So, we developed a simultaneous three-direction measurement system with three optical systems mixed the two-beam method. Using the new measurement system, the electric field vector distribution was measured in 0.1 minutes
