Abstract

The refractive index and absorption coefficient fields in participating media are reconstructed simultaneously in this work. In the direct model, the coupled radiation-conduction heat transfer in participating media exposed to a pulse laser irradiation is solved by finite volume method. In the inverse model, the sequential quadratic programming algorithm combined with the generalized Gaussian Markov random field model is employed to solve the reconstruction problem. It is found that the refractive index and absorption coefficient fields can't be reconstructed simultaneously. A secondary reconstruction technique based on different regularization parameters is proposed to reconstruct the refractive index and absorption coefficient fields simultaneously. All the retrieval results indicate that the proposed secondary reconstruction technique performs accurately and effectively.
