A new CCD3000 electro-optic measurement system based on Kerr electric-optic effect

A new measurement system is presented with Charge Coupled Device (CCD) sensor for electro-optic receiving and conversion based on the principle of Kerr electric-optic effect and theoretical analysis in this paper. It provides an effective method for the measurement of electric field and space charge distribution in liquid dielectric with small Kerr constant using CCD3000 with good stability, high sensitivity and wide dynamic range. According to experiments it can be concluded that the intensity of light corresponds with the electric field between the two parallel-plane electrodes in test cell in a certain range of the voltage applied. The conclusion reveals that the distribution and change tendency of the electric field between the two electrodes can be drawn by the analysis of the light intensity.
