超大望远镜的自适应光学

Adaptive Optics for Extremely Large Telescopes

Stefan Hippler

摘要:

自适应光学已成为目前正在建造或即将开始建造的最大地面望远镜的关键技术。自适应光学是一个必不可少的组成部分,基本上只有一个任务,那就是使望远镜以其最大角分辨率工作,而不因大气视宁度而造成光学退化。根据三十年来使用自适应光学的经验,所有的超大型望远镜及其仪器从一开始就设计用于衍射极限观测。本文介绍了极大望远镜、巨型麦哲伦望远镜和30米望远镜在设计中充分集成自适应光学的各种方法。文章最后简要介绍了高对比度成像对自适应光学的要求。

英文摘要:

Adaptive Optics has become a key technology for the largest ground-based telescopes currently under or close to begin of construction. Adaptive optics is an indispensable component and has basically only one task, that is to operate the telescope at its maximum angular resolution, without optical degradations resulting from atmospheric seeing. Based on three decades of experience using adaptive optics usually as an add-on component, all extremely large telescopes and their instrumentation are designed for diffraction limited observations from the very beginning. This review illuminates the various approaches of the Extremely Large Telescope, the Giant Magellan Telescope, and the Thirty-Meter Telescope, to fully integrate adaptive optics in their designs. The article concludes with a brief look into the requirements that high-contrast imaging poses on adaptive optics.
