Abstract

An all-weather NIR laser active imaging system with high power NIR pulse laser, image intensifier CCD (ICCD) camera and range-gated synchronization control technology is developed for acquiring longer detection range and high resolution image in adverse weather conditions. The system composition and working principle are introduced. The laboratory and outfield experiments have been done to validate imaging effect and imaging quality. The results show that the minimum resolution is about 5cm when observing the target far from 1200m in the dark of night and the image resolution could reach to 10cm when observing the target far from 2500m in misty condition. Furthermore, the minimum resolution is about 20cm when observing the target far from 4800m and the image is too blurred to accurately identify the target when observing the target far from 7200m in rainy condition. The system could be widely used in target reconnaissance, coastal patrol, search and rescue at sea, airports, ports, oil fields and forest fire prevention.
