摘要
在Rytov近似下 ,通过引入统计平均位错的概念研究了高斯光束通过近地面湍流大气传播时波前刃位错位置与湍流大气强度和传播距离等参数的关系。分别在远大于和远小于光波位相起伏周期的两种情况下 。
The relationship between the wave front edge-dislocation of a Gaussian beam propagating in a weak turbulent atmosphere and in near ground and the turbulent-strength,the distance of propagation have been discussed by the Rytov approximation.The formulas of the statistical average of wave front edge-dislocations have been developed in the cases that the averaging time is shorter than the fluctuation periodic time of wave front and the averaging time is longer than the fluctuation periodic time of wave front.
