摘要

摘要考虑了基于压电LiNbO3和LiTaO3双晶片结构的精确定位致动器。通过极限表面技术和有限元方法确定了确保最大可能位移的致动器板的最佳方向。将模拟的LiNbO3和LiTaO3板最佳取向的位移与实验获得的非最佳取向的LiNbO 3和LiTaO 3致动器的位移进行了比较。如图所示，致动器的最佳配置使我们能够显著增加LiNbO3和LiTaO3样品的位移。

Determination of optimal crystallographic orientations for LiNbO3 and LiTaO3 bimorph actuators

Abstract. The actuators for precise positioning based on bimorph structures of piezoelectric LiNbO 3 and LiTaO 3 crystals are considered. The optimal orientations of the actuator plates ensuring the highest possible displacements are determined by the extreme surfaces technique and the finite-element method. The simulated displacements for optimal orientations of LiNbO 3 and LiTaO 3 plates are compared with those obtained experimentally for manufactured LiNbO 3 and LiTaO 3 actuators, whose orientations are not optimal. As is shown, the optimal configuration of the actuator allows us to significantly increase its displacement for both LiNbO 3 and LiTaO 3 specimens.
