    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.
