MAORY 是用于欧洲极大望远镜的多共轭自适应光学中继模块。它将位于望远镜的 Nasmyth 平台上，为科学仪器提供数据。该模块应该以衍射受限的光学质量一对一地重新成像望远镜焦平面，并对大气引起的波前畸变提供多共轭自适应光学校正。该系统基于六颗用于感测波前畸变的激光导星和三个用于校正波前畸变的可变形镜。使用二向色镜将激光从科学和自然导星通道的光中分离出来。预计有两个输出端口，由二向色方向选择：一个处于重力不变配置，另一个处于垂直位置以向大型仪器供电。在本文中，介绍了当前的光学和机械设计以及热分析。
MAORY is the Multi-conjugate Adaptive Optics RelaY module for the European Extremely Large Telescope. It will be located on the Nasmyth platform of the telescope to feed scientific instruments. The module is supposed to re-image one to one the telescope focal plane with di raction limited optical quality and to provide multi-conjugate adaptive optics correction of the wavefront distortion induced by the atmosphere. The system is based on six laser guide stars for sensing the wavefront distortion and three deformable mirrors for correcting it. A dichroic is used to split the laser light from the light of the scientific and natural guide stars channel. Two output ports, selected by the dichroic orientation, are foreseen: one in a gravity invariant configuration and one in a vertical position to feed large instruments. In this article the current optical and mechanical design are presented together with the thermal analysis.
