提出了一种新颖的方法，即压缩蒙特卡罗模拟，该方法将给定反照率 mu(s)/(mu(a) + mu(s)) 的单个蒙特卡罗模拟结果应用于获得其他反照率的结果； mu(s) 和 mu(a) 分别是散射系数和吸收系数。该方法仅需要存储每个光子与介质相互作用的数量。因此，可以从有限数量的浓缩蒙特卡罗模拟中找到浑浊板的反射率和透射率。我们可以使用反演程序从板的总反射率和总透射率获得吸收和散射系数。对于所有反照率，半无限介质的发射光子密度作为光源和探测器之间距离的函数，甚至可以从单个凝聚蒙特卡罗模拟的结果中找到。相似性规则的应用可以进一步减少描述散射角分布对结果的影响所需的蒙特卡罗模拟的数量。
A novel method, condensed Monte Carlo simulation, is presented that applies the results of a single Monte Carlo simulation for a given albedo mu(s)/(mu(a) + mu(s)) to obtaining results for other albedos; mu(s) and mu(a) are the scattering and absorption coefficients, respectively. The method requires only the storage of the number of interactions of each photon with the medium. The reflectance and transmittance of turbid slabs can thus be found from a limited number of condensed Monte Carlo simulations. We can use an inversion procedure to obtain the absorption and scattering coefficients from the total reflectance and total transmittance of slabs. Remitted photon densities from a semi-infinite medium as a function of the distance between the light source and the detector for all albedos can be found even from the results of a single condensed Monte Carlo simulation. The application of similarity rules may reduce further the number of Monte Carlo simulations that are needed to describe the influence of the distribution of scattering angles on the results.
