Abstract
An optical voltage sensor with an arbitrary-electrical-field-direction-modulation mode is proposed to increase the half-wave voltage without bringing additional stress and birefringence. The mode is realized by heterogeneous electrodes arranged in a center-symmetric way, and generate an electrical field with a direction at an arbitrary angle to the light propagation direction. The finite element method and coupling wave theory are used to design and optimize the electrodes and field distribution. The experimental results show that heterogeneous electrodes and arbitrary electric field direction modulation mode is able to effectively regulate the Sensor's half-wave voltage and sensitivity, without degrading the accuracy and linearity. Compared to solid voltage divider method, this modulation mode almost do not generate additional temperature drift or measurement errors caused by birefringence, but have more simple structure, less drift and higher precision.
期刊介绍：
Measurement Science and Technology publishes articles on new measurement techniques and associated instrumentation. Papers that describe experiments must represent an advance in measurement science or measurement technique rather than the application of established experimental technique. Bearing in mind the multidisciplinary nature of the journal, authors must provide an introduction to their work that makes clear the novelty, significance, broader relevance of their work in a measurement context and relevance to the readership of Measurement Science and Technology. All submitted articles should contain consideration of the uncertainty, precision and/or accuracy of the measurements presented.
Subject coverage includes the theory, practice and application of measurement in physics, chemistry, engineering and the environmental and life sciences from inception to commercial exploitation. Publications in the journal should emphasize the novelty of reported methods, characterize them and demonstrate their performance using examples or applications.
