A theoretical and experimental study of the backscattering characteristics of a picosecond pulse scattered from a dense diffusing medium is presented. The theory uses a diffusion solution to the time-dependent equation of radiative transfer and the formulation of a picosecond range-gating technique. The experimental system consists of a high-power laser range-gating system, based on a picosecond Kerr-effect shutter. The results of experiments carried out on aqueous solutions of latex microspheres agree well with the theoretical calculations, not only in the pulse shape but in the relative magnitudes of the pulse height for different particle sizes and concentrations.
本文呈现了对从密集扩散介质散射的皮秒脉冲后向散射特性的理论与实验研究。该理论采用了辐射传输时间相关方程的扩散解以及皮秒距离选通技术的公式。实验系统由基于皮秒克尔效应快门的高功率激光距离选通系统组成。在乳胶微球水溶液上进行的实验结果与理论计算吻合良好，不仅在脉冲形状方面，而且在不同粒径和浓度下脉冲高度的相对大小方面。
