将高斯光束通过角反射器的传输过程简化为其连续通过2个平行四边形光阑的传输过程，利用广义惠更斯‐菲涅尔衍射积分以及将硬边光阑窗口函数展开为有限个复高斯函数之和的方法，推导了双程大气湍流条件下高斯光束通过角反射器的近似三维解析传输公式。数值计算表明，当入射角较大时反射光的平均光强分布模式的畸变明显，且在同等数值时入射角带来的畸变效应大于方位角带来的畸变效应；远场情况下，除了一些小的旁瓣的存在反射光光强分布的主瓣具有较好的高斯模式。

Based on the idea that the propagation of Gaussian beams passing through a cube cor‐ner reflector can be approximately regarded as a propagation of Gaussian beams passing through two parallelogram apertures in turn ,and by using the extended Huygens‐Fresnel diffraction integral ,and the method of expanding the aperture function into a finite sum of complex Gaussian functions ,an ap‐proximate analytical propagation formula of Gaussian beams propagating through a cube corner reflec‐tor in turbulent atmosphere is derived and illustrated with numerical examples .It is found that the aberrance of the average intensity distribution pattern becomes obvious with the increase of the inci‐dence angle ,and the aberrance brought by the incidence angle is larger than that by the orientation an‐gle at same values .In far field conditions ,the main petal of the average intensity distribution has a good Gaussian pattern ,besides some lateral petals .
