Exoplanet High Resolution Spectrograph

该项目旨在实现所谓的EXOhSPEC原型摄谱仪（系外行星高分辨率摄谱仪）。它将完全由目录组件建造，但将利用天文光谱仪中没有部署的技术。EXOhSPEC将在实验室、当地自动望远镜以及加那利群岛和泰国的望远镜上对太阳和当地恒星进行测试。一个版本是注定要交付给泰国国家望远镜。它的目的是具有尽可能少的光学表面的高分辨率光谱仪和它的效率和小尺寸将使它成为一个非常有吸引力的进一步发展。在几个新的发展，我们介绍的是主动计量，使我们能够构建一个小型的非热光谱仪从现成的部分。该项目的长期目标是能够建立一个原型，以大大扩大精确径向速度的范围，提高精度和效率，例如能够实现天基径向速度仪器。有一篇论文描述了早期的结果，并列出了该项目的未来步骤（Jones等人，2021）沿着软件，以实现通过多个设计的迭代。

This project is to realise the so-called EXOhSPEC prototype spectrograph (Exoplanet high resolution spectrograph). It will be entirely built from catalogue components but will utilise technologies not deployed in astronomical spectrographs. EXOhSPEC will be tested on the Sun and local stars both in the laboratory, on local automated telescope as well as with telescopes in the Canaries and Thailand. A version is destined for delivery to the Thai National Telescope. It is intended to have the fewest possible optical surfaces for a high resolution spectrograph and its efficiency and small size will make it a highly attractive for further development. Among several novel developments that we introduce is active metrology which enables us to construct a small athermal spectrograph from off-the-shelf parts. The long-term aim of the project is to be able to build a prototype to significantly extend the reach of precision radial velocities to higher precisions and efficiencies enabling for example a space-based radial velocity instrument. A paper describing early results and laying out future steps for the project is available (Jones et al., 2021) along with software to enable iteration through a number of designs.
