【 摘 要 】

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.
