美国自适应光学路线图以实现Astro2020目标

US Adaptive Optics Roadmap to Achieve Astro2020

Julian Christou, Mark Chun, Richard Dekany, Philip Hinz, Jessica Lu, Jared Males, Peter Wizinowich

AI总结:

该路线图基于Astro2020报告,确定自适应光学(AO)为关键技术,提出发展优先事项,以支持美国极大望远镜(ELT)项目及现有望远镜升级,并强调可见光AO的潜力与挑战。

摘要:

在最近的Astro2020十年报告《2020年代天文学与天体物理学发现之路》中,自适应光学(AO)被认定为一项关键技术,原因多种多样。其中包括强调高对比度成像和AO系统作为未来技术发展的一部分,尤其适用于美国两个极大望远镜(ELT)项目。此外,报告还确定了现有4米至10米级望远镜的仪器升级,这些升级将包括对现有AO系统的改进。正如报告所指出的:(1)“AO仪器化的核心作用及其进一步开发的重要性正在迅速增长,新概念推动向更广区域发展”;(2)“可见光AO通过开辟整个波长范围的高角分辨率研究,具有很高的科学回报潜力。其目标是利用光学波段望远镜更小的衍射极限,然而在较短波长下,相干长度和时间均减小,需要在空间和时间频率上以高频率进行波前传感,这在当前技术上具有挑战性。这是2020年代至2030年代的一个重要发展领域”;(3)“对AO系统开发的此类投资是ELT的关键风险缓解策略,因为ELT的完全分辨率和灵敏度潜力只有通过AO才能实现,并且这被认为是GMT和TMT最重要的技术风险”。\n2023年5月举办了一次研讨会,以制定一份社区响应文件(即本文件),向各资助机构(如NSF、NASA和DOE)提供反馈和建议优先事项,以确定AO研究与发展优先事项,以满足Astro2020为地基AO(无论是独立运行还是支持太空任务)所设定的技术和科学目标。

英文摘要:

In the recent Astro2020 Decadal Report, ''Pathways to Discovery in Astronomy and Astrophysics for the 2020s'' Adaptive Optics (AO) was identified as a crucial technology for a variety of reasons. These included an emphasis on high-contrast imaging and AO systems as being part of future technology development especially with application to the two US ELT projects. Instrument upgrades were also identified for existing 4m to 10m class telescopes which would incorporate upgrades to existing AO systems. As noted in the Report: (1) ''the central role of AO instrumentation and the importance of further development are rapidly growing, with novel concepts pushing toward wider area'', (2) ''Visible AO has high potential scientific return by opening up an entire wavelength regime to high angular resolution studies. The goal is to exploit the smaller diffraction limit of telescopes in the optical, yet both the coherence length and time decrease at shorter wavelengths requiring wavefront sensing at high spatial and temporal frequencies that are currently technologically challenging. This is an important developing area for the 2020s - 2030s.'', and (3) ''Such investments in AO systems development is a key risk mitigation strategy for ELTs, whose full resolution and sensitivity potential can only be realized with AO, and which is recognized as the most important technical risk for both GMT and TMT''. A workshop was held in May, 2023 to develop a Community Response document (this document) to provide feedback and suggested priorities to various funding agencies, such as NSF, NASA, and DoE, as to the AO Research and Development priorities to meet the technical and science objectives outlined in Astro2020 for ground-based AO, both stand-alone and in support of space missions.
