摘　　要：像增强器作为微光夜视装备的核心器件,其动态范围研究具有重要意义。论述了基于自动门控电源的微光像增强器动态范围扩展的意义,分析讨论了自动门控电源MCP电压、阴极脉冲宽度、阴极脉冲频率、阴极开启电压与微光像增强器动态范围的关系,提出了微光像增强器动态范围估算模型。As image intensifier being the core device of LLL night vision device, its dynamic range has a great significance for study. The thesis discusses the significance of enlarging image intensifier dynamic range based on auto-gating power source, then analyzes the relationships of image intensifier dynamic range with MCP voltage, cathode pulse width, cathode pulse frequency and the cathode turn-on voltage, ultimately the calculation model of image intensifier dynamic range is achieved.
