摘要: 针对匹配自动门控电源的超二代像增强器高低温条件下亮度增益和最大输出亮度产生漂移的问题，分析了温度补偿原理，设计了温度补偿方案，通过实验确定了温度补偿系数，验证了该温度补偿方案的合理性。实验结果表明，低照条件（输入照度低于5×10－4 lx），通过将MCP电压降低14.7 V能够将低温（－45℃）亮度增益从121%降低到105%以内，通过将MCP电压增加16.5 V能够将高温（55℃）亮度增益从77%提高到99%以上；高照条件（输入照度高于5×10－4 lx），通过将阳极电流设定值降低14%能够将低温最大输出亮度从114%降低到104%以内，通过将阳极电流设定值增加12.6%能够将高温最大输出亮度从87%提高到91%以上。因此，采用本文所述温度补偿技术能够有效提高自动门控像增强器高低温条件下亮度增益和最大输出亮度的一致性。Abstract: The brightness gain and maximum output brightness of super gen Ⅱ auto-gated image intensifiers vary with temperature. Here, we analyzed the principles of temperature compensation and designed a temperature compensation scheme. The compensation coefficient was determined experimentally, and the rationality of the temperature-compensation scheme was verified using the data. The experimental results showed that the low temperature (-45℃) brightness gain can be reduced from 121% to 105% by reducing the MCP voltage by 14.7 V under low illumination conditions (input illumination is less than 5×10-4 lx), and the high temperature (55℃) brightness gain can be increased from 77% to 99% by increasing the MCP voltage by 16.5 V. Under high illumination conditions (input illumination of more than 5×10-4 lx), the maximum output brightness at low temperatures can be reduced from 114% to less than 104% by reducing the anode current setting value by 14%, and the maximum output brightness at high temperature can be increased from 87% to more than 91% by increasing the anode current setting value by 12.6%. Therefore, the temperature compensation technology described herein can effectively improve the consistency of the brightness gain and maximum output brightness of auto-gated image intensifiers under high- and low-temperature conditions.
