The effect of a clear layer at the surface of a diffusive medium on measurements of reflectance and transmittance has been investigated with Monte Carlo simulations. To quantify the effect of the clear layer Monte Carlo results have been fitted with the solution of the diffusion equation for the homogeneous medium in order to reconstruct the optical properties of the diffusive medium. The results showed that the clear layer has a small effect on measurements of transmittance. On the contrary measurements of reflectance are greatly perturbed and the accurate reconstruction of the optical properties of the diffusive medium becomes almost impossible.
通过蒙特卡罗模拟研究了扩散介质表面的透明层对反射率和透射率测量的影响。为了量化透明层的影响，已将蒙特卡罗结果与均匀介质扩散方程的解进行拟合，以重建扩散介质的光学特性。结果表明，透明层对透射率测量的影响较小。相反，反射率测量受到极大干扰，几乎无法准确重建扩散介质的光学特性。
