论文摘要
MCAO辅助可见成像仪和光谱仪（MAVIS）自适应光学模块具有非常苛刻的目标，可以在光学上支持科学的目标：在V频段中以30arcsec直径的大型FOV在Paranal的标准大气条件下提供15％SR。它将能够在最多三个天然导向星降至H = 19的封闭环上工作，从而在南银河杆上提供大于50％的天空覆盖率。这样的目标和大型MCAO系统参数空间的探索需要分析和最终模拟的组合，以评估性能，天空覆盖范围并推动设计。在这项工作中，我们报告了基线性能，统计的天空覆盖率和参数敏感性分析在A期仪器研究中进行的。
The MCAO Assisted Visible Imager and Spectrograph (MAVIS) Adaptive Optics Module has very demanding goals to support science in the optical: providing 15% SR in V band on a large FoV of 30arcsec diameter in standard atmospheric conditions at Paranal. It will be able to work in closed loop on up to three natural guide stars down to H=19, providing a sky coverage larger than 50% in the south galactic pole. Such goals and the exploration of a large MCAO system parameters space have required a combination of analytical and end- to-end simulations to assess performance, sky coverage and drive the design. In this work we report baseline performance, statistical sky coverage and parameters sensitivity analysis done in the phase-A instrument study.
