摘要。从理论上和实验上分析了浑浊介质的弹道和扩散两种状态之间的过渡对探测系统实验立体角的依赖关系。建立了一个简单的模型，说明了实验条件对弹道扩散跃迁位置的重要性。结果表明，减小实体角会扩大弹道范围；然而，这种好处受到初始高斯光束衍射的限制。此外，根据模型的原理选择合适的波长提供了另一种扩展弹道状态的方法。因此，通过优化实验条件，应该可以提取厚度为1 cm的组织的弹道图像。
Abstract. The dependence of the transition between the ballistic and the diffusive regimes of turbid media on the experimental solid angle of the detection system is analyzed theoretically and experimentally. A simple model is developed which shows the significance of experimental conditions on the location of the ballistic–diffusive transition. It is demonstrated that decreasing the solid angle expands the ballistic regime; however, this benefit is bounded by the initial Gaussian beam diffraction. In addition, choosing the appropriate wavelength according to the model’s principles provides another means of expanding the ballistic regime. Consequently, by optimizing the experimental conditions, it should be possible to extract the ballistic image of a tissue with a thickness of 1 cm.
