摘要
对实际湍流大气中的激光强度起伏进行了系统的实验观测，详细分析了光强起伏的强度、概率密度分布与功率谱的统计特征及其周日、全年变化规律．同时分析了探测器件的饱和效应对实验结果的影响．
We carried out a series of measurments of the irradiance scintillation of a He Ne laser beam propagating through a real turbulent atmosphere in a whole year. The statistical properties of the irradiance scintillation, such as the scintillation index, the probabitity distribution, and the power spectrum were analysed. The effect of detector saturation on the accuracy of the measurment data was discussed.
