摘要：

Experiments are performed that illustrate the scattering and reradiation of damped traveling waves of light energy density from objects within otherwise homogeneous turbid media. We demonstrate that simple diffractive and refractive models can be used to understand the scattering of these waves by absorptive and dispersive spheres. Furthermore, using a fluorescent dye we can reestablish the origin of the diffuse photon density waves, by converting from one optical and diffusive wavelength to another while maintaining phase coherence. The possibilities for precise medical imaging are presented.
