摘要

光散射技术通常用于表征悬浮在浑浊介质中的颗粒,蒙特卡罗模拟是许多此类方法的重要组成部分。在这项工作中,我们使用蒙特卡罗方法模拟了光在由不同类型的粒子组成的浑浊混合物中的传播,并得到了相关的概率分布,发现这与文献报道的工作一致。利用模拟模型提出了一种只需测量散射功率和透射功率即可确定双分散混合物中组成粒子浓度的方法。该方法在聚苯乙烯球混浊混合物的实验中得到了验证,在实验误差范围内是准确的。

Method to determine the concentrations of constituents in a bidisperse turbid medium using Monte Carlo simulation for mixtures
Light scattering techniques are often used to characterize the particles suspended in a turbid medium, and Monte Carlo simulations are an important part of many such methodologies. In this work, we use the Monte Carlo method to simulate the propagation of light in a turbid mixture, that comprises of different types of particles, and obtain the relevant probability distributions, which are found to be consistent with the works reported in the literature. The simulation model is used to propose a recipe which requires a single measurement of the scattered power and the transmitted power, to determine the concentrations of constituent particles in a bidisperse mixture. The method is experimentally validated for turbid mixtures of polystyrene spheres, and found to be accurate within the limits of experimental error.
