摘　　要：采用有限元法对几种不同电极结构下电光偏转器的电场分布进行研究.设计出一种具有较大偏转角度的超越曲面电极结构电光偏转器,与圆柱电极结构和双曲面电极结构电光偏转器的性能对比,可知此种电光偏转器的偏转角度更大,电场梯度线性度更高·The electric field distributions of electro-optic deflectors with several different electrodes was studies by the finite element method. A new deflector with hypersurface electrode structure and bigger deflection angle is designed. Compared with the deflectors based on cylindrical electrode structure and hyperboloid electrode structure, it is shown that the new designed electro-optic deflector has bigger deflection angle and higher linearity of electric field gradient.
