Abstract

We have developed a technique to estimate the absorption coefficient (μ a) distribution of turbid medium using the backscattered light, and verified its feasibility in simulations and experiments. For accurate estimation of μa, accurate scattering property (μ's) is essential. Here, we newly developed the simultaneous estimation technique for μ's and μ a by attaching the diffuser plate with known μ's and μ a. The validity of the proposed technique was verified in simulation. The accuracy was apparently improved.
