AI 中文摘要
这项工作提出了一种用于FLEX光纤定位器的新型粘滑压电致动器，以应对在下一代多目标光谱仪器（如宽视场光谱望远镜（WST））中在减小尺寸的同时保持精度的挑战。该致动器结合了紧凑的几何形状（直径3.2毫米，长度小于70毫米）以及高分辨率增量运动、低功耗和高可靠性。三个致动器可集成到直径小于7毫米的圆中，实现简化的单平面组装。此设计为宽视场光谱应用中的小型化、精确光纤定位提供了一个有前景的解决方案。
英文摘要
This work presents a novel stick-slip piezoelectric actuator for the FLEX fibre positioner, addressing the challenge of reducing footprint while maintaining precision in next-generation multi-object spectroscopic instruments such as the Wide-field Spectroscopic Telescope (WST). The actuator combines compact geometry (3.2 mm diameter, sub 70 mm length) with high-resolution incremental motion, low power consumption, and high reliability. Three actuators can be integrated into a sub 7 mm diameter circle, enabling a simplified, single-plane assembly. This design offers a promising solution for miniaturized, accurate fibre positioning in wide-field spectroscopic applications.
