AI 中文摘要
集成了可变形镜（DM）的望远镜的出现，给自适应光学（AO）系统带来了新挑战。由于DM和波前传感器（WFS）间距较大，二者之间的对准关系在运行过程中会定期变化。若不进行跟踪和校正，DM与WFS之间的这些错位会导致环路不稳定，无法实现衍射极限性能。SPRINT提供了一种在观测期间跟踪这些错位的方法，可恢复旋转、平移和放大错位。目前大型双筒望远镜（LBT）缺乏跟踪此类错位的可行方案，而SPRINT已被选为即将推出的极大望远镜（ELT）上若干仪器的基线方法。我们报告了将SPRINT集成到LBT实时计算机中的情况，并展示了白天和天基测试的实验结果以验证该方法。
英文摘要
The advent of telescopes with an integrated deformable mirror (DM) presents new challenges for adaptive optics (AO) systems. The alignment between the DM and wavefront sensor (WFS) is expected to regularly evolve during operations due to their large separation. Without tracking and correction, these mis-registrations between the DM and WFS lead to loop instability, preventing diffraction limited performance from being realised. SPRINT\cite{heritier2021} provides an approach to track these mis-registrations during observations. Rotation, shift, and magnification mis-registrations can all be recovered. The Large Binocular Telescope (LBT) currently lacks an operational solution for tracking these mis-registrations, while SPRINT has been selected as the baseline approach for several instruments on the forthcoming Extremely Large Telescope (ELT). We report on the implementation of SPRINT into the LBT real time computer and present experimental results from both daytime and on-sky testing to validate the method.
