【摘要】 研究了数字型彩色CMOS图像传感器的γ射线辐照效应。采用不同γ射线注量进行积累辐照和单次辐照。积累辐照后捕获的图像在1.2kGy时变得非常差,而单次辐照后图像在1.8kGy时才变得非常差。积累辐照由于类似加电模式而比单次辐照时性能退化严重。更多还原

【Abstract】 Radiation effect of color CMOS digital image sensors was studied by accumu-lative radiation and sing1e dose radiation at different γ-ray doses. The quality of the pic-ture captured under natural lighting is very poor only at 1.2 kGy for accumulative radia-tion, but at 1.8 kGy for single dose radiation, showing that the radiation-induced degra-dation of the device performance for the sensor with accumulative γ-ray doses is muchmore severe than those with single dose due to like power-on mode.更多还原
