| Outline of Final Research Achievements |
In this research, we develop a novel optical tomography method that can model multiple scattering that is closer to reality than isotropic scattering or simple scattering. The purpose of this research is to analyze the scattering of infrared light inside the object using the method used in computer graphics, and to solve the inverse problem by computer vision approach and estimate the inside of the object. In this study, the internal structure of the object (that is, the extinction coefficient of light at each point) is estimated by observing the light emitted from the upper part of the object and observing the light emitted from the lower side of the object. This problem was formulated as a constrained optimization problem using an approximate layer multiple scattering model, and an efficient calculation method was devised.
