Reconstruction optical spectroscopy using transient radiative transfer
equation and pulsed laser: a numerical study
(2005)Abstract
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 nonhomogeneous 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.
