Influence of Refractive Index on Reflectance from a Semi-Infinite Absorbing-Scattering Medium with Collimated Incident Radiation
Directional and hemispherical reflectance and transmittance, which result from collimated incident radiation on a semi-infinite absorbing-scattering medium, are presented as a function of refractive index and scattering albedo. Exponential kernel substitution is used to develop an approximate but closed form solution to the governing transport equation. It is considered that scattering is isotropic and that the Fresnel relations govern the interface reflection and transmission. Exact solution, available only for normally incident radiation, reports hemispherical reflectances that are within 15 per cent of the predicted values. © 1975.
