Description

technical field

[0001] The invention belongs to ultraviolet detection technology, in particular to an ultraviolet image intensifier. It can be used in space environment, space target detection and ultraviolet early warning. It can also be used for public security security, authenticity identification, cultural relic identification, etc. Background technique

[0002] Ultraviolet early warning is an advanced missile early warning technology. Compared with pulse Doppler radar early warning, ultraviolet early warning is passive early warning and has good concealment; compared with infrared early warning, ultraviolet early warning equipment has a low false alarm rate and does not require Refrigeration, small size and light weight and other advantages. Ultraviolet early warning is to use the ultraviolet band of the "solar spectrum blind zone" to detect the flame and plume of the missile. Because it is not sensitive to sunlight and ordinary light, it can avoid the largest backgro...
