本文给出了混浊介质中球形不均匀体对漫射光子密度波散射的解析解。分析结果与实验测量进行了比较。理论和实验之间的密切协议允许使用的理论，以确定未知的球形物体嵌入混浊介质中的属性。分析解决方案扩展到包括几个问题的实际利益成像，包括多个源，多个对象，和边界的影响，对球形不均匀性的表征。我们还扩展了解决方案，包括时域测量。
We present an analytic solution for the scattering of diffuse photon density waves by spherical inhomogeneities within turbid media. The analytic result is compared to experimental measurements. Close agreement between theory and experiment permits the use of the theory to determine the properties of unknown sphere-like objects embedded in turbid media. The analytic solution is extended to encompass several problems of practical interest in imaging, including the influence of multiple sources, multiple objects, and boundaries on the characterization of spherical inhomogeneities. We also extend the solution to encompass time-domain measurements.
