论文摘要
毛里（Maory）是欧洲ELT的多偶联自适应光学接力，旨在为Micado提供1个Arcmin校正场，Micado是一种近红外的镜像，侧重于星形标准。在本文中，我们重新查看了为当前自适应光学体系结构和子系统要求的主要要求和分析。我们讨论了波段错误预算分配，重点是最坏的罪犯术语以及对它们对大气和钠概况的依赖的统计分析。我们提出了对主要AO参数的权衡研究的更新修订，这些研究以及来自光学和机械子系统的考虑因素也被用来定义仪器的初步设计。
MAORY is the Multi-conjugate Adaptive Optics RelaY for the European ELT aimed at providing a 1 arcmin corrected field to MICADO, a near-infrared spectro-imager with a focus on astrometry. In this paper we re-view the main requirements and analysis that justify the current adaptive optics architecture and subsystem requirements. We discuss the wavefront error budget allocation focusing on the worst offenders terms and on a statistical analysis of their dependence on atmospheric and sodium profiles. We present an updated revision of the trade-off studies on the main AO parameters that, along with considerations coming from optical and mechanical subsystems, are used to define the preliminary design of the instrument.
