混浊介质中从弹道到扩散的转变
The transition from the ballistic to the diffusive regime in a turbid medium
摘要：
通过在准一维实验中改变Intraperoid-India油墨溶液的吸收系数和宽度，研究了弹道和扩散状态之间的过渡。本文从实验和理论两方面分析了在同一平均自由程内，介质的衰减系数在两个不同值之间突变的问题，并证明了突变位置不仅与测量立体角有关，而且与散射系数有关。
英文摘要：
By varying the absorption coefficient and width of an intralipid- India ink solution in a quasi one-dimensional experiment, the transition between the ballistic and the diffusive regimes is investigated. The medium's attenuation coefficient changes abruptly between two different values within a single mean-free-path. This problem is analyzed both experimentally and theoretically, and it is demonstrated that the transition location depends on the scattering coefficient as well as on the measuring solid angle.
