N2 - Optical Computed Tomography (OCT) is available for 3-D distribution of solution's refractive index. The 3-D distribution can be fitted up with divers 2-D slices. Thus, the discrete mathematical model of 3-D refractive index data reconstruction can be framed in a linear ill-posed problem. We proposed a practical reconstruction algorithm, Modified SART with Changing Relaxation Factor based on Simulated Annealing algorithm (CRF-MART), which is a modification of Simultaneous Algebraic Reconstruction Technique (SART). Furthermore, a computer simulation of the reconstruction algorithm was taken in the case of incomplete data. It is shown that reconstructed results have better smoothness and smaller residual, which are a good approximation to the true value.
