Abstract
Traditional methods for determining the optical properties of turbid media are implemented in diffusive regimes, where the scattering coefficient and anisotropy factor are inseparable due to the similarity relation for anisotropy scattering. Determining and in addition to the absorption coefficient normally requires measurements using thin samples or media of low scattering, which are inappropriate for in vivo applications. In this work, we propose an analytical method to simultaneously recover , , and based on the incomplete P5 approximation () to the continuous wave (CW) radiative transport equation. The proposed method was verified using both simulated and experimental data with the relative errors less than 6.6%, 11.6%, and 8.2% for ranging , ranging , and ranging 0.61–0.81, respectively. Since the -based radiance method can be easily implemented with several measurements, it is expected to be used for recovering a full set of the optical properties in vivo.
