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.
