研究并对比了6类电荷耦合器件和互补金属氧化物半导体图像传感器的辐射响应均匀性。设计辐射实验,对像素阵列中响应信号在不同统计区域内的像素值增量平均值和非均匀度进行分析与讨论,重点研究了各类固态图像传感器像素阵列全局、区域和代表像元的辐射响应均匀性。实验结果表明:在稳态γ射线辐射场辐照条件下,帧图像中的响应信号增量并非固定值;像素阵列各区域内响应信号的均匀性不因辐照剂量率的变化而变化,对于相同的图像传感器,辐射在任意帧图像中产生辐射响应信号的分布与像素阵列中任意像素在多帧图像中出现辐射响应的分布相同,但由于传感器的本底噪声存在差异,单个像元、区域像素的统计结...

Herein, the radiation response uniformities of six types of charge-coupled devices and complementary metal-oxide-semiconductor image sensors are studied and compared. Irradiation experiments are performed to investigate the average incremental pixel values and nonuniformities of radiation response signals in different regions of the pixel array. The radiation response uniformities of the global pixel array, regional pixels, and typical pixels in various solid-state image sensors are mainly studied. Results show that the incremental pixel value ...
