利用飞秒激光和条纹相机技术对随机介质后向散射脉冲的时间分布进行了实验研究。对于弱散射介质，后向散射脉冲的时间分布可以用简单的指数函数来描述。在强散射制度的时间分布成为非指数。由散射和吸收引起的衰减长度可以直接从后向散射脉冲的时间分布的分析中确定。
The temporal profiles of the backscattered pulse from random media are studied experimentally with femtosecond laser and streak-camera technologies. For a weakly scattering medium, the temporal profile of a backscattered pulse can be described by a simple exponential function. In the strongly scattering regime the temporal profile becomes nonexponential. The attenuation lengths arising from scattering and absorption can be directly determined from an analysis of the temporal profile of the backscattered pulse.
