Resumo: This work presents the differential evolution algorithm applied to an inverse radiative transfer problem formulated as a finite dimensional optimization problem. It is considered a one-dimensional isotropically-scattering medium with finite optical thickness, space-dependent scattering albedo and plane-parallel geometry. The direct radiative transfer problem models the transmission of radiation through this medium by a linear version of the Boltzmann equation with azimuthal symmetry. The direct radiative transfer problem solution, which is required for the optimization techniques, is obtained by using the collocation method. Some test cases are presented, aiming at illustrating the efficiency of the methodologies used in the treatment of an inverse problem of radiative transfer. The results are compared with other approaches and indicate that the proposed methodology characterizes a promising methodology for dealing with this type of inverse problem.
