Modeling of optical radiation interaction with multiple scattering mediums

Mathematical model of optical radiation interaction with multiple scattering medium is build with consideration of medium structural heterogeneity, its spectral properties and fluorescence effects. Developed model is implemented for Henyey-Greenstein phase function. The approximate solution based on expansion in perturbation series of diffuse and fluorescent fluxes of transport equation is proposed. The application of spherical harmonics approximation of first order for description of optical radiation interaction with multiple scattering mediums is investigated. The comparative analysis of approximate model shows its correspondence with physical experimental data.
