Imaging the diffusion coefficient in a parabolic inverse problem in optical tomography.
(English)
[J] Inverse Probl. 15, No.2, 373-397 (1999). ISSN 0266-5611

Summary: The elliptic systems method, previously developed by the second and third authors, is extended to the reconstruction of the diffusion coefficient of an inverse problem for the parabolic equation $u_t= \text{div}(D(x)\nabla u)$ in the $n$-dimensional case $(n= 2,3)$. This inverse problem has applications to optical imaging of small abnormalities hidden in a random media, such as biological tissues, foggy atmospheres, murky water, etc. Results of numerical experiments are presented in the two-dimensional case, for realistic ranges of the parameters.
