A hybrid inversion scheme combining Markov chain Monte Carlo and iterative methods for determining optical properties of random media

24 Aug 2019 Jiang Yu Hoshi Yoko Machida Manabu Nakamura Gen

Near-infrared spectroscopy (NIRS) including diffuse optical tomography is an imaging modality which makes use of diffuse light propagation in random media. When optical properties of a random medium is investigated from boundary measurements of reflected or transmitted light, iterative inversion schemes such as the Levenberg-Marquardt algorithm are known to fail when initial guesses are not close to the true value of the coefficient to be reconstructed...
