摘　　要：针对传统上像增强器输出信噪比测试条件的不完备性,阐述了亮度增益对输出信噪比的影响,在不同增益条件下利用设计的像增强器信噪比测试仪对输出信噪比进行了测试,验证了在输出信噪比测试中亮度增益标定的必要性。In view of the incompleteness of the condition in testing image intensifier's output signal-to-noise ratio, the brightness gain's effect on output signal-to-noise ratio is expounded. The output signal-to-noise ratio is tested by using a designed test system of output signal-to-noise ratio in different gains. The necessity of calibrating the brightness gain is validated.
