| Outline of Final Research Achievements |
The objectives of this study were to examine light propagation in biological tissue with fine structure using the radiative transfer equation, and to determine the optical properties of the tissues using an inverse algorithm.
Firstly, an accurate and efficient numerical scheme was developed for solving the radiative transfer equation in highly forward-directed scattering media such as biological tissue.From the numerical results of the RTE, the transition length and time from ballistic light to diffusive light were evaluated as a function of the optical properties. Secondly,the time-resolved profiles of light in agricultural and food products were measured and the in-vivo and ex-vivo optical properties of them were evaluated using the inverse analysis. It was suggested the optical properties were related with the structural properties.
