研究人员在《天文学期刊》发表论文，介绍了一款计算机工具来解决现代天文望远镜的机械盲点问题1。现代大型巡天望远镜依靠数千个微型机器人定位光纤以收集来自遥远星体的光线，但这些机器人在密集星系区域容易相互碰撞，导致部分星系被跳过1。新开发的工具通过模拟机器人运动，帮助天文学家识别并改进仪器设计，进而构建更准确的宇宙地图1。
研究团队提出了三个关键优化规则来提升观测完整性1。首先，最小间距设置能够同时提供最佳的完整性和效率；其次，增加机器人覆盖范围是改进的第二佳方法；此外，减小安全间隙虽然也有帮助但效果相对较小1。未来望远镜计划同时使用超过20,000个微型机器人1。该计算机工具可在望远镜建造前进行测试，能够节省数百万美元的成本1。
Astronomers have published a computational tool designed to address a significant limitation in modern large-scale survey telescopes, according to research presented in The Astrophysical Journal1. Contemporary observatories rely on thousands of tiny robotic positioners that direct optical fibers to capture light from distant celestial objects, but these mechanisms create observation gaps when robots collide or become constrained in densely populated star-field regions1.
The new software works by simulating robot movements to help researchers identify which galaxies might be missed during observations and to refine instrument designs accordingly1. The research team identified three core optimization strategies: maintaining optimal minimum spacing between robots delivers the best balance of completeness and efficiency; expanding the overall coverage area of robot deployments represents the second-most effective improvement; and reducing safety margins between units provides additional but more modest gains1. Future telescope projects plan to deploy over 20,000 of these miniature robotic positioners simultaneously1, making such optimization critical for constructing accurate maps of the universe.
The computational tool enables astronomers to test and validate designs before construction begins, potentially saving millions of dollars in development costs1.
