Abstract

For the current brightness gain and maximum output brightness adjustment method of image intensifier has low efficiency, time-consuming, low precision, and other problems, this paper firstly studies a communication protocol from the perspective of digital communication of auto-gating power supply microcontroller. By means of communication with the host computer, the corresponding parameters of the internal program of the auto-gating power supply microcontroller are adjusted. Secondly, the hardware interface of the whole tube communication of the image intensifier is designed. Finally, the calibrated experimental device is used to adjust the brightness gain and maximum brightness of the whole tube, and the automatic brightness control function of the adjusted whole tube is verified. The adjustment time is short, the adjustment precision is high, and the matching between the auto-gating power supply and the image tube can be better realized.
