综述了近年来微光像增强器发展的现状和动向.目前微光器件主要向第四代近贴聚焦像增强器发展,其技术突破一是采用无膜MCP;二是光电阴极采用自动门控电源和红外热像与微光夜视光学融合技术.夜视仪向小巧、轻便和价廉的单兵头盔及单甲双目手持微光眼镜和微光轻**瞄准仪发展.最后指出微光器件寿命是实现实用化的关键.

The article summarized the status quo and trend of the low-light-level image intenssifier in the recent years. Now,the development of low-light-level devices will be in the direction towards IV generation proximity focus image intensifier. The breakthrough of its technology at two points has made as follows:(1) the use of uncoated MCP;(2) the use of fusion technology of IR thermal imaging and low-light-level night vision for the photocathode. Night vision instruments are advancing towards small-sized, portable and cheap one-man helmet-mounted displays and monocular/binocular night visions,and light arm sights.The life of LLL device is the key problem which we have to solve for applications.
