给“千里眼”配“角膜”,天文望远镜能看多远?(上)| 中科院长春光机所张舸

from 中科院格致论道讲坛

如果把大型光学望远镜比作“千里眼”,那么主反射镜就是这只“千里眼”的核心部件——“角膜”。张舸研究员的工作就是给“千里眼”配上“角膜”。随着技术的进步,要求光学仪器的分辨率越来越高,希望光学仪器看得越远,看得越清楚,为此张舸研究员和他的团队克服了一系列技术难题成功研制出世界最大口径的碳化硅反射镜坯,为中国国防建设和空间探测与开发事业的发展起到了无与伦比的推动作用。 “SELF格致论道”是中国科学院全力推出、中国科普博览承办的科学讲坛,致力于精英思想的跨界传播。登陆官方网站(self.org.cn)、微信公众号“SELFtalks”获取更多信息。
