基于压电陶瓷实现光纤定位的关键技术方法研究

This paper references the Subaru telescope’s Echidna fiber positioning units, and makes a research on the key technology of optical fiber positioning method based on piezoelectric ceramic actuator. Piezoelectric ceramic has the advantages of high precision and high speed. This paper studies Echidna’s fiber positioning units, and build a laboratory envirenment to control it accurately. What's more, this paper comes up with a new fiber positioning method with no blind area based on two-dimension piezoelectric ceramic workbench. This study could provides a new method for the construction and upgrading of astronomical telescope.

本项目借鉴研究Subaru的Echidna光纤定位系统，研究基于压电陶瓷实现光纤定位的关键技术方法。对Echidna的压电陶瓷定位单元进行研究，研究压电陶瓷的性质以及驱动和控制，搭建实验室环境对其压电陶瓷执行器实现精确控制，实现精确定位。同时提出一套基于二维压电陶瓷平台的光纤定位方案，创造性的提出利用杠杆位移放大原理消除定位盲区，并对压电陶瓷二维平台进行精确定位控制。本项目的顺利开展研究将为我国望远镜光纤定位系统的升级改造提供一种新的思路以及相关技术储备。
