Abstract
This paper presents the optical tomography based on the reconstruction of optical properties in one- and two-dimensional variable index media. A transient discrete transfer method is used to solve the forward problem of transient radiative transfer. A multistart conjugate gradient method is applied to solve the inverse problem, and a straightforward approach is used to obtain the sensitivity coefficients. Different numerical examples are presented to show the efficiency of this method. The results show that the proposed algorithm can effectively estimate the distribution of absorption and scattering coefficients, even with noisy measured data.
