中文摘要：

成像系统动态空间分辨率的下降与静态相比主要发生在光阴极与微通道板输入面之间。本文采用时空传递函数理论，分析了动态下空间分辨率的下降因子，计算得到的结果与实验结果相比基本一致，提出了进一步提高系统性能的方法。

英文摘要：

The dynamic resolution of imaging system will degrades between photocathode and MCP. Utilizing temporal-spatial translation function theory, the degrading factor of dynamic resolution is analyzed. The theory result is consistent with experiment. The method to improve the performance of imaging system is also discussed.
