Development and prospect of lowlightlevel (LLL) night vision technology

Lowlightlevel (LLL) night vision technology, as one of main high military optoelectronic technologies, will become more and more outstanding and important, and will possess enormous potential and wide application in the modern or future high technology war and night fighting along with the technologies fast developing and the performances continuous improving for LLL night vision devices and systems. Based on the detailed analyses of the tube characteristics，main ideas and key technologies of the Super Gen. Ⅱ, Gen. Ⅲ and Gen.Ⅳ image intensifiers, the development status and uptodate progress are introduced and expatiated in this paper. Simultaneously, some prospects and suggestions about developing direction and main research work for domestic LLL night vision technology are put forward according to the internal situation such as the condition of equipments, the performance of devices and the level of technologies.
