摘　　要：超二代像增强器与三代像增强器长期保持着并行发展的态势,但迭代性能划定和命名之争也贯穿其发展历程。随着多碱光电阴极的光谱拓展取得实质性突破,同时无膜微通道板在一些GaAs光阴极像增强器中也成为可能,像增强器的“代”已彻底失去意义,可对各自所能达到的实际使用性能仍然缺乏一个全面准确的评判。通过回顾像增强器的发展历程及其标志性的迭代性能突破,和随之多次引发的迭代性能划定和命名之争,进一步说明标准规范在准确评价像增强器的迭代性能特征及其实际使用性能方面存在不足,同时,数字化可集成的夜视技术是未来的发展趋势,数字像增强相机也已成为像增强技术的一种新的产品形态,像增强器的标准更新及其性能参数与实际使用性能对应关系的研究已经显得很有必要。The Gen 2 image intensifier is keeping a parallel technology development status with the Gen 3 image intensifier and the debate over the generation division and performance upgrade is also accompanying their development.Over time,as substantial breakthroughs for multi-alkali photocathode in the extended spectral range occur,as well as the development of filmless micro-channel plates(MCP)in some GaAs photocathodes image intensifiers,the term“Generation”for image intensifiers has arguably lost meaning.However,there is still lack of accurate comparison assessments for the filed performance that both generations have achieved.Though the existing military specification cannot fully reflect the upgraded image intensifier characteristic and its actual field performance,standards updates as well as investigations of the link between these characteristic parameters and the actual field performance are necessary.
