摘要：
The range-gated imaging system combines the technologies of pulsed laser illuminating and range-gated ICCD. To measure and evaluate the resolution of range-gated imaging system under certain atmosphere conditions, a simulating measurement setup is designed. Two light sources are used for simulating the signal and backscatter light respectively. Based on the method of equivalent irradiance on photo-cathode, the methods of power calculation and power range determination for simulating light sources are provided. In the case of image intensifier using S-20 photo-cathode coupled with CCD, based on the model of optical backscatter and signal for range-gated imaging system, the power of simulating light sources are calculated.
