Abstract
The transport of visible and near infrared (MR) photons through dense random media has been the subject of intense recent interest.1 Important practical aspects of these problems concern the potential uses of diffusing MR light fields to locate objects within turbid media. To this end, photon migration patterns derived from a variety of probes have been employed to study the effects of inhomogeneities on optical path lengths in turbid media. In this paper we discuss recent methods whereby amplitude modulated continuous-wave NIR light sources2 are used to provide imaging information about spatial inhomogeneities within turbid media.
