| 摘 要： | 对空间辐射环境下PIN光电探测器γ射线辐射特性以及粒子辐射特性进行了深入的研究。结果表明两种辐射机制均会对PIN光电探测器造成一定的影响,表现为暗电流噪声增加、响应率下降以及响应带宽下降。在卫星光通信系统结构设计过程中应该更多地考虑空间辐射对暗电流噪声造成的影响。

| Abstract: | As the key terminal,the performance of PIN detector affects the stability and reliability of the optical satellite communication system.The properties of γ radiation and particle radiation of PIN detector under space radiation environment were researched.The results show that both radiation mechanisms impose effects on PIN detector,expressing as the increase of dark current noise and decrease of both responsivity and response bandwidth.It is indicated that the influence of space radiation on dark current noise should be the first factor to be considered in the design of optical satellite communication system. |

| Keywords: | space radiation PIN detector dark current responsivity response bandwidth |
