在长距离无线光通信中,接收点光功率密度与光束发散角平方呈反比关系,为了获得小的发散角和大的功率耦合效率,要求准直系统有较大的数值孔径,但数值孔径过大会增加像差,因此合理设计功率耦合效率与准直系统的数值孔径就非常重要。

When the receiving aperture is much larger than the scattering disk scale, the aperture-smooth effect is remarkable and the derived variance approximates the result given by weak-fluctuation theory for any zenith; when the receiving aperture is much smaller than the scattering disk scale, the low-pass filter effect of the scattering disk scale is dominating and weak-fluctuation theory is valid only for small zeniths.

散射盘尺度和接收孔径对到达角起伏起平滑作用,当接收孔径远大于散射盘尺度时,由于孔径平滑作用,导出的表达式在任意天顶角都可以近似为弱起伏理论给出的结果;当接收孔径小于散射盘尺度时,散射盘尺度的平滑作用明显,接收孔径的平滑作用相对较小,传统的到达角起伏理论仅在小天顶角是适用的,在大天顶角必须用新导出的方差表达式。
