4.1米SOAR望远镜的自适应模块，SOAR自适应模块（SAM），使用紫外激光引导星星校正地面层湍流。它于2013年投入使用，自2014年以来一直在正常的科学运作中。SAM与覆盖3“视场的CCD成像器或散斑相机配合使用。它的工作常规和稳定，提供等于自由大气视宁度的I波段分辨率。本文介绍了SAM系统作为一个整体，其用户和仪器感兴趣的技术信息提供必要的参考。本文介绍了该仪器的工作原理、性能特点以及迄今为止用SAM进行的科学研究项目。
The adaptive module of the 4.1 m SOAR telescope, SOAR Adaptive Module (SAM), corrects ground-layer turbulence using an ultraviolet laser guide star. It has been commissioned in 2013 and it is in regular science operation since 2014. SAM works with the CCD imager covering a 3′ field or with the speckle camera. It operates routinely and stably, delivering resolution in the I band equal to the free-atmosphere seeing. This paper describes the SAM system as a whole, providing essential reference for its users and technical information of interest to instrumentalists. Operation of the instrument, its performance, and science projects done with SAM so far are reviewed.
