The evaluation of conventional light-scattering experiments in turbid media is often highly complicated because of the presence of multiple scattering contributions. The three-dimensional (3-D) cross-correlation method presented provides an effective and handy method to suppress the influence of multiply scattered light. As the time dependence of the 3-D cross-correlation function is determined solely by the singly scattered light, the evaluation of the decay constant yields reliable values for the effective diffusion coefficient and the hydrodynamic particle size of the suspended particles. Furthermore, analysis of the amplitude of the 3-D cross-correlation function permits the determination of the differential scattering cross section even for highly turbid suspensions.
由于存在多次散射贡献，对混浊介质中的传统光散射实验进行评估往往非常复杂。所提出的三维（3-D）互相关方法提供了一种有效且便捷的方法来抑制多次散射光的影响。由于三维互相关函数的时间依赖性仅由单次散射光决定，因此对衰减常数的评估可为悬浮颗粒的有效扩散系数和流体动力学粒径提供可靠值。此外，对三维互相关函数幅度的分析甚至可以确定高度混浊悬浮液的微分散射截面。
