摘要

在寻找宇宙生命的过程中，对类地系外行星的研究是现代天文学中最深刻、最具哲学魅力的焦点之一。这里描述的范式转换研究需要一种新型的可扩展空间望远镜，它可以重新定义空间中可用的光收集区域。由多阶衍射光学(MODE透镜)支持的鹦鹉螺空间天文台正在引领大型太空望远镜透镜的出现，这些望远镜旨在寻找上千个系外地球上的生物特征。开发了运动啮合轭系统(KEYS)来对准MODE镜头的分段版本。建立了KEYS的技术演示样机，并采用扫描白光干涉法和偏转法对其进行了测试。还开发了一个偏转测量系统，以监测其在UV(即紫外线)固化期间的分段模式透镜的闭环对准。

Kinematically engaged yoke system for segmented lens-based space telescope integration and testing

One of the most profound and philosophically captivating foci of modern astronomy is the study of Earth-like exoplanets in the search for life in the Universe. The paradigm-shifting investigation described here calls for a new type of scalable space telescope that redefines the available light-collecting area in space. The Nautilus Space Observatory, enabled by multiple-order diffractive optics (the MODE lens), is ushering in the advent of large space telescope lenses designed to search for biosignatures on a thousand exo-earths. The Kinematically Engaged Yoke System (KEYS) was developed to align a segmented version of the MODE lens. A technology demonstration prototype of KEYS was built and tested using scanning white light interferometry and deflectometry. A deflectometry system was also developed to monitor the closed-loop alignment of the segmented MODE lens during its UV (i.e., Ultraviolet) curing.

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
