针对微光像增强器在高照度条件下会出现图像饱和的问题, 提出将基于 PLD器件的门控技术应用于微光像增强器电源中。论述了微光像增强器门控技术、光阴极门控原理、以及 PLD器件应用于门控技术中的原理和实现方法。给出了阴极门控设计原理电路和试验结果。

For the problem that image saturation will be emerged at high illumination conditions, this paperfirstly puts forward a gating technique based on the PLD device that can be applied to image intensifiers.Secondly, the low-light-level image intensifier gating technique, photocathode gating principle and theprinciple and implementation method of PLD device applied to gating technique are discussed in this paper.Finally this paper provides the principle circuit design of gated photocathode and test results.
