为选择能用于γ射线辐照环境且最具有加固潜力的图像传感器模组,对比分析了7类传感器模组辐照前后实时采集明、暗图像的参数,研究了不同类型的模拟图像传感器模组及数字图像传感器模组的抗辐射性能,并讨论了辐射损伤机理。实验结果表明:γ射线对图像传感器模组的损伤及干扰程度与模组类型、图像传感器制作工艺、辐照剂量率及总剂量相关;剂量率造成的干扰与剂量率并非呈单纯的线性关系;镜头透镜的透光率随累积剂量的增大而下降;入射γ射线对采集画面质量的干扰与环境光线强度相关,较弱的真实信号更易被入射光子引入的噪声淹没。以上结果提示,入射γ射线对图像传感器的损伤及干扰主要是由各像素单...

In order to select the type of image sensor module which is suitable for γ-ray irradiation environment and has the most potential ability for radiation hardening, seven types of image sensor modules were studied by analyzing the parameters of bright and dark images before and after irradiation. The radiation resistance of different types of analog and digital image sensor modules was studied, and the radiation damage mechanism was also discussed. The experimental results show that the damage and interference degree of the image sensor module i...
