摘要
空间光学敏感器/探测器是航天器的重要组成部分或重要类型,然而大量存在的空间荷电粒子会造成探测器件本底噪声及性能损伤,对空间探测任务产生不良影响。目前对空间荷电粒子的影响缺乏定量评估手段,广泛采用的质量屏蔽、磁偏转和反符合技术在空间荷电粒子屏蔽方面均存在局限性。在对上述方法进行综述的基础上,提出了基于电磁复合场的空间光学敏感器/探测器荷电粒子屏蔽装置的设计思路。
Spatial optical sensor detector is an important component or type of a spacecraft,but the abundant existing spatial charged particle would cause background noise and performance degradation to the sensor detector,affecting space exploration task.Currently,there lacks quantitative evaluation method for the impact of spatial charged particle.Besides,there is limitation for the widely used mass shielding,permanent magnet deflection and anticoincidence technology in shielding spatial charged particle.So,this paper reviews the researches about the problem,and provides a novel design thought about spatial charged particle shielding system for spatial optical sensor detector based on electric magnetic complex field.
