为了捕捉宇宙X射线——“天关”卫星大视场聚焦成像技术攻坚纪实
Ke Ji Ri Bao· 2025-12-18 03:30
日前,从中国科学院国家空间科学中心传来一系列关于"天关"卫星的好消息:发现新型X射线暂现天 体,为理解这类神秘暂现天体提供关键线索;探测到银河系内X射线暗弱爆发天体,为人类发现恒星级 黑洞开辟新途径…… 浩瀚苍穹中,那些遥远、暗弱又转瞬即逝的宇宙X射线,是人类探秘宇宙的重要线索。要想捕捉这些射 线,必须拥有能看得广、看得远、看得清的"眼睛",而这正是"天关"卫星具备的重要特点。 "取得这些发现,主要归功于我们为'天关'卫星量身定制的微孔龙虾眼X射线聚焦成像技术。"中国科学 院国家天文台研究员、"天关"卫星首席科学家袁为民向科技日报记者介绍,该技术不仅让卫星具备极大 的视场——一次定点观测即可覆盖约十一分之一天区,还大幅提升了卫星的探测灵敏度和定位精度,让 其性能远超国际同类设备。 细磨"广角镜" 为什么要给卫星装上"龙虾眼"?这就要从龙虾的眼睛说起。 中国科学院国家天文台研究员张臣介绍,龙虾的眼睛拥有广阔的视野和独特的聚焦机制,里面有无数细 小的方管,管壁光滑,且全部指向同一个中心。光线射入后,经管壁反射,能精准聚焦到视网膜上。 美国天文学家基于此提出设想:模仿龙虾的眼睛,研制一台既可覆盖大视场又能聚焦的X射 ...

日前,从中国科学院国家空间科学中心传来一系列关于"天关"卫星的好消息:发现新型X射线暂现 天体,为理解这类神秘暂现天体提供关键线索;探测到银河系内X射线暗弱爆发天体,为人类发现恒星 级黑洞开辟新途径…… "主要原因是技术难度太大。"张臣解释,X射线的能量极高,很容易穿透观测设备,无法像可见光 那样,通过反射或折射实现聚焦。因此,想让"天关"卫星拥有"龙虾眼",关键是要造出结构类似于龙虾 眼睛的聚焦镜头,而镜头的核心则是镜片。 "当时这种镜片只有法国一家公司能够生产,可对方不仅报价高昂,还无法保证质量。"张臣告诉记 者,"最后我们下定决心,走自主研发这条路!" 恰在这时,团队曾调研过的北方夜视技术股份有限公司主动上门,提出希望合作研制"龙虾眼"光学 器件。双方一拍即合,镜片研制工作驶入快车道。 浩瀚苍穹中,那些遥远、暗弱又转瞬即逝的宇宙X射线,是人类探秘宇宙的重要线索。要想捕捉这 些射线,必须拥有能看得广、看得远、看得清的"眼睛",而这正是"天关"卫星具备的重要特点。 "取得这些发现,主要归功于我们为'天关'卫星量身定制的微孔龙虾眼X射线聚焦成像技术。"中国 科学院国家天文台研究员、"天关"卫星首席科学家袁为民 ...
