AI 中文摘要
巨型麦哲伦望远镜极端自适应光学（GMagAO-X）仪器现已被选定为巨型麦哲伦望远镜（GMT）仪器套件的正式组成部分，该仪器将在2030年代中期GMT首次光观测时投入使用，目前正推进至最终设计阶段，计划于2027年3月开展最终设计评审。带有21000个促动器的高密度促动器变形镜将使GMagAO-X能够生成从可见光到近红外的衍射极限图像，GMagAO-X将与高性能日冕仪耦合，用于在衍射极限下搜寻系外行星，而该日冕仪需要亚纳米精度的波前控制。本文将更新波前传感与控制架构的相关内容，以及各控制回路如何通过端到端仿真实现相互作用。
英文摘要
The Giant Magellan Adaptive Optics eXtreme (GMagAO-X) instrument has now been selected as an official part of the Giant Magellan Telescope's (GMT) instrument suite. The instrument will be ready at first-light of the GMT in the mid 2030s. The instrument is now progressing towards its final design with a final design review planned for March, 2027. The high-density actuator deformable mirror with 21.000 actuators will allow GMagAO-X to create diffraction-limited images from visible to near-infrared. GMagAO-X will be coupled with high-performance coronagraphs to search for exoplanets at the diffraction-limit. The coronagraphs require wavefront control at sub-nm precision. We will provide an update on the wavefront sensing and control architecture and how the loops interact with each other through end-to-end simulations.
