The Latest Development of Low-Light-Level Image Intensifier

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.
