Paper Abstract

First order perturbation approach to the diffusion equation provides a more realistic model to describe inhomogeneous structures. To this regard, we obtained a general expression of the time-resolved transmittance relatively to a homogeneous turbid medium with an embedded inclusion. This expression was further approximated in the case of a small volume object. Then, we studied the limit and accuracy of this approach concerning on a cubic absorber placed in the centre of the source-detector line of a turbid slab.
