【摘要】 光学遥感是当前卫星遥感的重要手段,而卫星温控和能源系统也广泛采用光学膜层,它们在空间环境条件下的性能对卫星应用任务的完成,乃至卫星寿命、安全将起着非常重要的作用.本文给出了太阳紫外辐射对星上光学膜层影响的主要机制,分析了这一影响的主要规律和原子氧剥蚀、高能粒子和静电场的作用,综述了太阳紫外辐射对星上光学系统表面膜层影响的测量结果,最后提出了星上光学膜层污染防护中应重点关注的几个方面.更多还原

【Abstract】 Optical remote sensing is an important means for spaceborne remote sensing,and optical films also have been applied widely in temperature control and energy supply systems of satellite. Their performance in space environment plays an important role for satellite operation in orbit, especially for satellite life and safety.This paper gives the physical mechanisms of the effects of solar UV radiation on optical films,and analyses its rule of this effects.In addition,the influences of atom oxygen erosion,energetic particles and electrostatic charging on the optical films degradation induced by under solar UV irradiation have been analyzed.The experimental results about the effects of solar UV radiation on space-based optical system coatings are also reviewed.Finally the suggestions for contamination protection are provided.更多还原
