NASA兰利研究中心、复合光学公司和Nyma/ADF联合开发了一种用于空间遥控望远镜的可展开主镜，该主镜结合了五年多来对光学精密结构部署的研究和十多年来光学精密复合镜板和结构制造技术的发展。这种可展开的反射镜可直接应用于一类非成像“激光雷达”(光向和测距)望远镜，其图形误差要求在1到10微米RMS的范围内。此外，反射镜的设计可以很容易地进行修改，以适应成像质量的反射板和用于成像望远镜的有源面板调整控制机构。本文：1)介绍了可展开镜的概念；2)阐述了可展开镜的发展现状；3)提供了直径2.55米的概念验证镜的一些技术指标。
NASA Langley Reseach Center, Composite Optics, Inc., and Nyma/ADF have developed jointly a deployable primary mirror for space telecsopes that combines over five years of research on deployment of optical-precision structures and over ten years of development of fabrication techniques for optical-precision composite mirror panels and structures. The deployable mirror is directly applicable to a broad class of non-imaging "lidar" (light direction and ranging) telescopes whose figure-error requirements are in the range of one to ten microns RMS. Furthermore, the mirror design can be readily modified to accommodate imaging-quality reflector panels and active panel-alighment control mechanisms for application to imaging telescopes. The present paper: 1) describes the deployable mirror concept; 2) explains the status of the mirror development; and 3) provides some technical specifications for a 2.55-m-diameter, proof-of-concept mirror.
