Estimation of optical properties by spatially resolved reflectance spectroscopy in the subdiffusive regime.

摘要: We propose and objectively evaluate an inverse Monte Carlo model for estimation of absorption reduced scattering coefficients similarity parameter γ from spatially resolved reflectance (SRR) profiles in the subdiffusive regime. The carries additional information on phase function that governs angular properties turbid media. SRR at five source-detector separations were acquired with optical fiber probe. was based a cost enabled robust few measurements without priori knowledge about spectral dependencies properties. Validation performed synthetic datasets measured phantoms comprising molecular dye polystyrene microspheres. observed substantially variability arising significantly improved accuracy model. However, improvement extended limited to exceeding ∼15  cm −1 , where relative root-mean-square errors estimated well within 10%.
