A laser range-gated imaging system, which can be used to eliminate backscattering in environments with strong scattering (dense aerosol), is developed based on two high-speed technologies. It uses high-power, ultra-short-pulse laser (350 ps and 40 uJ) as the light source. It opens the optical gate of the ICCD camera with a micro-channel plate (MCP) image intensifier in a notably short time (approximately 200 ps), and the laser pulses that are reflected by the object return to the ICCD camera. Using this range-gated imaging technology, the effect of scattered light can be reduced, and a clear image is obtained. In this paper, the verification test results of the RGI (range-gated imaging) system, which simulates a severe accident situation of nuclear power plants, are described in dense aerosol (fog) environments. To verify the monitoring performance of the RGI system in a dense fog environment, we made the test facility (2.5 m × 2.5 m × 15 m, WHD). The fogs were injected into the test facility until the fog concentration was saturated. In identical fog concentration conditions, we compared the monitoring performances of the RGI system and color CCD camera.
