介绍了行间转移面阵CCD芯片KAI-1010M的内部结构、工作时序和驱动系统,采用将存储区内相同像素在不同曝光时间的感应电荷叠加,实现了行间转移面阵CCD的时间延时和积分工作方式;采用Fast Dump Gate(FDG)功能快速清除电荷而只保留3行CCD信号以提高帧频,克服面阵帧周期长的缺点,实现三线阵工作方式,最终实现了三线阵的时间延时和积分成像工作方式.实验结果表明,此实现方式是可行的,最大帧频可达54.3 fps,控制曝光时间的方式灵活,而且能使CCD输出信号的幅度成倍的增加.

After introducing to the inner structure,driver timing and driver system of a interline area-CCD KAI-1010M being are introduced briefly.The corresponding charges accumulation in the VCCD realizes interline CCD's TDI mode:the FDG function iS adopted to clear the unused CCD signals to increase frame rate for overcoming the area-CCD's long period,achieving the three-lines camera features,and finally achieving the TDI three-lines camera features.The results show that the TDI three-line camera's working mode is realizable,its frame rate can be up to 54.3 fps,exposing time can be changed in several ways,and this way can double the CCD output signal.
