Method for measuring locally and surface properties scattering and absorption of turbid media.

摘要

Method for local and superficial characterization, on a probed volume and measuring area with dimensions on the order of a transport mean free path, of a turbid medium using the following parameters: a) the refractive index n of the turbid medium. b) the absorption coefficient of the turbid medium. c) the reduced scattering coefficient ìs¿ the turbid medium. d) the function parameter phase = (1-g2) / (1-g1) of the turbid media, where g1 and g2 are the first two moments of the Legendre polynomial development of the phase function ñ (è ), representing said ñ (E) function the probability density for the scattering angle è, which comprises the following steps: - measuring the spatially resolved reflectance R (n) of the turbid medium, N being the source-detector distance by any means, comprising an illumination beam as a source and an optical detector, which allows determination of said spatially resolved reflectance R (N), - mathematically processing R (n) to compute at least said parameters IA, ìs¿ , to.
