Abstract
The enhanced generation of a spontaneous Raman signal by way of elastic scattering is demonstrated. Using Monte Carlo simulations, we show that elastic scattering, by increasing the path length of light through the medium, enhances the generation of a Raman signal. This is investigated over a large parameter space, demonstrating that this effect is robust, and providing additional physical insight into the dynamics of light propagation in a turbid medium. Both the temporal and spatial profiles of the Raman signal are shown to depend heavily on the amount of scattering present.
摘要
通过弹性散射增强自发拉曼信号的产生得到了证明。利用蒙特卡罗模拟，我们表明弹性散射通过增加光在介质中的传播路径长度，增强了拉曼信号的产生。这在一个大的参数空间中进行了研究，证明了这种效应是稳健的，并为浑浊介质中光传播的动力学提供了额外的物理见解。拉曼信号的时间和空间分布都显示出强烈依赖于存在的散射量。
