详细研究了部分相干平顶（PCFT）光束通过大气湍流时的偏振态，即偏振椭圆的大小、形状和方向。研究了不同源条件对PCFT光束在大气湍流中偏振态的影响。基于随机电磁波束偏振态的统一理论，建立了随机电磁波束偏振态变化的详细计算公式。研究了不同源条件下任意阶平顶光束N通过大气湍流时PCFT光束的偏振态行为。
The polarization states, i.e. the size, the shape and the orientation of the polarization ellipse of partially coherent flat-topped (PCFT) beams passing through atmospheric turbulence are studied in detail. The effects are studied of different source conditions on the polarization states of a PCFT beam propagating through atmospheric turbulence. Based on the unified theory of the polarization states for random electromagnetic beams, we have established the detailed formula for calculating the change of the polarization states of such beams.The polarization states behavior of PCFT beams passing through atmospheric turbulence for any arbitrary order of a flat-topped beam “N” under different source conditions were investigated.
