| Abstract: | 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. |
