Abstract

The spherical harmonics methods (classical and modified) can be used to solve the radiative transport equation in series form. However, the evaluation of the truncated series for the angular radiance near sources or boundaries is known to be a difficult or partly an impossible task. In this conference paper, we report on a hybrid P_N-method which enables the evaluation of the angle-resolved radiance at the boundary of an anisotropically scattering medium. The number of spherical harmonics required under the use of the hybrid model is reduced significantly compared with the classical or modified spherical harmonics method.
