SINOPSIS

Reconstruction optical spectroscopy is highly dependent on the radiative transfer model used to track radiative energy propagation in semi-transparent materials. In this paper, it is intended to present a numerical tool adapted for treating radiative transfer in the frame of short-pulsed laser beam interaction with non-homogeneous matter and to show how this numerical tool can undergo inversion through non-linear adjoint treatment or reverse differentiation. The effects of measurements filtering on the accuracy of the reconstruction are also investigated. It is found that the inversion of the forward model is reliable and that the temporal treatment of the measurements increases the efficiency of the reconstruction.
