Angularly resolved reflectance from random and aligned semi-infinite media

Abstract

The angularly resolved reflectance from semi-infinite turbid media is investigated using the Monte Carlo method. Turbid media with random and aligned microstructures are considered. It is shown that in the case of random media the Lambert law is valid for one special configuration of the optical and geometrical properties. For random media having an aligned microstructure the angularly resolved total reflectance is completely different from a Lambertian characteristic.
