Polarized light propagation in a multiple scattering medium is governed by the vector radiative transfer equation. We analyze the vector radiative transfer equation in asymptotic limit of forward-peaked scattering and derive an approximate system of equations for the Stokes parameters, which we call the vector Fokker-Planck approximation. The vector Fokker-Planck approximation provides valuable insight into several outstanding issues regarding the forward-peaked scattering of polarized light such as the polarization memory phenomenon.
偏振光在多重散射介质中的传播由矢量辐射传输方程控制。我们在向前峰值散射的渐近极限下分析矢量辐射传输方程，并推导了斯托克斯参数的近似方程组，我们称之为矢量福克 - 普朗克近似。矢量福克 - 普朗克近似为关于偏振光向前峰值散射的几个突出问题提供了有价值的见解，例如偏振记忆现象。
