Abstract

A general solution for the radiance distribution inside a sphere is developed for nonuniform, nonlambertian diffusely scattering surfaces. This provides a method for investigating the surface scattering transfer characteristics or the initial irradiance distribution. It is demonstrated that the surface structure and reflectance variations affect the classical radiant flux photometric measurement. Using specific reflectance patterns, it is possible to measure specific spherical harmonic moments of the initial irradiance distribution.
