标题： A multi-functional fiber positioning system for Extremely Large Telescopes

摘要： 我们提出了一个针对多目标高分辨率光谱学的光纤定位系统概念设计，旨在与即将出现的具有宽视场的大望远镜兼容。 该设计结合了多个大气色散校正器（ADC）和倾斜反射镜，这些元件接收来自单个目标的非离轴输入，并将其导向ADC。 在这里，我们介绍了一种机械设计方案，该方案适应光学系统并在曲焦平面上运行，其曲率半径（R）为3米。 此机械设计提供了四个自由度以访问焦平面体积，从而提高目标效率。 所提出的系统设计和高效的观测目标分配算法可确保主要观测会话的目标效率约为80%-100%。 我们还提出了一种基于顺序和蒙特卡洛（MC）算法的目标分配、定位和量化方法。 该方法已在具有不同目标密度的实际场中进行了测试，以验证其性能。 显示英文摘要

摘要： We present a conceptual design for a fiber positioning system for multi-object high-resolution spectroscopy, designed to be compatible with the upcoming large telescopes with a wide field of view. The design incorporates multiple Atmospheric Dispersion Correctors (ADCs) and tip-tilt mirrors that receive non-telecentric input from individual targets and direct it to the ADCs. Here, we introduce a mechanical design for the fiber positioner that accommodates the optics and operates in a curved focal plane with a Radius of Curvature (R) of 3m. This mechanical design provides four degrees of freedom to access the focal volume, enhancing targeting efficiency. The proposed design and an efficient target allocation algorithm ensure a targeting efficiency of approximately 80-100% for a primary observation session. We also present a methodology for target assignment, positioning, and quantification based on sequential and Monte Carlo (MC) algorithms. This method has been tested on realistic fields with varying target densities to validate its performance.
