Abstract
A night vision device (,) includes an improved power (,) that regulates the output brightness of the image intensifier tube (,) of the device (,) according to the two functions of MCP voltage control and photocathode gating duty cycle control. These two functions operate in sequence—the MCP voltage control operates prior to the duty cycle control with increasing input illumination to the image intensifier—in order to provide automatic brightness control and bright source protection while maximizing the high light level image resolution and maintaining the signal-to-noise ratio of the image intensifier at an acceptably high level.
