Measurement of two-dimensional electric field distribution in liquid dielectric using Kerr effect

Abstract

We have designed an electric field distribution measurement system using electric field modulation and a video camera, and have used the system to measure DC electric field distribution in nitrobenzene. We obtain a lower measurement level of E/sub dc/=200 V/cm. The resolution of the measurement system is about 12 bits, and for higher sensitivity measurement we need to use a higher resolution D/A converter.
