摘　　要：用概率理论研究了湍流大气中传播激光束心抖动概率分布和抖动导致点孔检测平均光强起伏概率分布．结果表明，二维束心抖动概率满足Ｒｉｃｉａｎ分布而点孔检测平均光强的起伏满足Ｇａｍｍａ分布．The probability distribution of the beam-centre wanders and the probabilitydistribution of the fluctuating average intensity measured by the point-aperture and causedby beam wander have been studied by using the probability theroy for laser beampropagation in a turbulent atmosphere. The resultS shown, the probability distribution ofthe two-dimension beam wandrs obeys Rician distribution, and the probability distributionof the average intensity fluctuations measured by the point-aperture satisfies Gammadistribution.
