Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
摘要：
2017年9月在荷兰莱顿的洛伦兹中心举行的最佳光学日冕仪研讨会聚集了一个由25名研究人员组成的多元化小组，致力于系外行星仪器的研究，以刺激新想法的出现和分享。这篇文章是总结讲习班成果的三篇系列论文的最后一部分，概述了为地面和空间望远镜的高对比度成像仪器而实施或考虑的新型光学技术和系统。高对比度仪器的总体目标是在最高10^-10的对比度水平上提供对系外行星的直接观测和表征。我们列出了当前技术的缺点，并确定了新技术的机会和发展路径，使性能实现了飞跃。具体来说，我们讨论了设计和制造的关键部件，如先进的可变形反射镜和日冕光学，以及它们的融合在“自适应日冕”系统。此外，我们讨论了高度集成的系统设计，结合对比度增强技术和表征技术（如高分辨率光谱），同时最大限度地减少整体复杂性。最后，我们将探索使用地面望远镜的全光子解决方案和空间望远镜的专用大孔径的极端实现。
英文摘要：
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumentation to stimulate the emergence and sharing of new ideas. This contribution is the final part of a series of three papers summarizing the outcomes of the workshop, and presents an overview of novel optical technologies and systems that are implemented or considered for high-contrast imaging instruments on both ground-based and space telescopes. The overall objective of high contrast instruments is to provide direct observations and characterizations of exoplanets at contrast levels as extreme as 10^-10. We list shortcomings of current technologies, and identify opportunities and development paths for new technologies that enable quantum leaps in performance. Specifically, we discuss the design and manufacturing of key components like advanced deformable mirrors and coronagraphic optics, and their amalgamation in "adaptive coronagraph" systems. Moreover, we discuss highly integrated system designs that combine contrast-enhancing techniques and characterization techniques (like high-resolution spectroscopy) while minimizing the overall complexity. Finally, we explore extreme implementations using all-photonics solutions for ground-based telescopes and dedicated huge apertures for space telescopes.
