A fast and novel perturbation approach is proposed to account for the effects of absorbing inhomogeneities on light propagation through layered media. The calculation has been implemented with the Born approximation. Examples of results are reported both for a two- and for a three-layered medium. The method presented has been validated with the results of Monte Carlo simulations. The forward solver presented in this paper can be of significant use in investigating the feasibility of real experiments, e.g. for functional imaging studies.
