MAORY将是多自适应光学模块，为超大望远镜（ELT）的高分辨率相机和光谱仪MICADO提供第一缕光线。为了确保MICADO视场上的高均匀图像质量和高天空覆盖，基线是使用六颗钠激光导星进行波前传感。激光导星波前传感器（LGS WFS）是用于实时测量高阶星波前畸变的MAORY子系统。在本文中，我们描述了MAORY LGS WFS的当前设计，包括光力学，权衡和可能的未来改进。
MAORY will be the multi-adaptive optics module feeding the high resolution camera and spectrograph MICADO at the Extremely Large Telescope (ELT) first light. In order to ensure high and homogeneous image quality over the MICADO field of view and high sky coverage, the baseline is to operate wavefront sensing using six Sodium Laser Guide Stars. The Laser Guide Star Wavefront Sensor (LGS WFS) is the MAORY sub-system devoted to real-time measurement of the high order wavefront distortions. In this paper we describe the MAORY LGS WFS current design, including opto-mechanics, trade-offs and possible future improvements.
