Abstract

The paper presents a theoretical analysis and experimental verification of a lithium niobate electrooptic sensor for measurement of DC electric fields in a space charge environment. Both unipolar and bipolar charge environments were investigated. In both cases the sensor output is linearly dependent on the measured electric field and independent of the density of space charge. Temperature stability of the sensor was analyzed and a novel compensation model is proposed
