With the view toward the realization of optical CT imaging, we have developed the simultaneous estimation technique of scattering (μ's) and absorption (μa) distributions and verified the feasibility in simulation. The usefulness of the proposed technique was verified in experiment with three-layer-structure models. The μa estimation error was less than 20% in the range of μ's = 0.75 – 2 /mm. Through this analysis, the usefulness of the proposed technique was verified.
