The low light level remote sensing imaging technology uses image intensified CCD (ICCD),to make up of the existing CCD remote sensing camera. The technology features are wide spectral response, low noise, high sensitivity, large dynamic range, and intelligent electronic control. The ICCD as well as its applications, will significantly expand the applicable luminance conditions and work time of various spacecraft, from 10~5-10~2 lx in the daytime (10:0016:00 for 6 h effective remote sensing time) to 10~5-10~(-1) lx under daylight/dawn/dusk/moonlight conditions (06:00-18:00 for 12 h effective remote sensing time). The remote sensing equipment can provide real-time information in a wider period through its observing, reporting, and early warning ground emergencies, such as natural disasters, terrorist activities, as well as some necessary demands in geography, geology and mapping fields. In the paper, we have reviewed the basic principle, system composition, key technique, performance test, overall evaluation and the latest research progress and achievement in application of the low light level remote sensing imaging technology.
