摘要 CCD图像传感器作为高灵敏度光电集成部件,易受空间辐射的影响而发生性能退化和工作异常。开展其辐射效应评价研究并制定相应的防护对策,是保证其在空间可靠应用的前提。文章通过地面模拟试验和辐射屏蔽计算,对空间用CCD图像传感器电离辐射损伤与位移损伤效应开展评估方法研究,为CCD抗辐射加固设计与地面评估试验提供参考。该方法也可用于其他光电器件和材料辐射效应评价。 As a highly sensitive integrated optoelectronic component, the CCD image sensors are susceptible to space radiation damages, which would result in the performance degradation and anomalies of the CCD devices. It is a prerequisite for the reliable application in a space system to evaluate the radiation response of the CCD devices and to adopt corresponding radiation-hardness strategies. In this paper, an evaluation method by the ground simulation test and the calculation of the radiation shielding is proposed for the ionizing radiation damage and the displacement damage effects of the CCD devices, so that a reference method can be provided to deal with the radiation-hardness design and the on-ground evaluation experiments. The method can also be used to evaluate the radiation effects of other types of optoelectronic devices and materials.
