Abstract
A method includes simultaneously illuminating a material using multiple first radiances and measuring multiple second radiances from the material. Each second radiance includes at least a portion of two or more first radiances that have interacted with the material. The method also includes determining a structure of the material based on the measurements. The first radiances may be directed at the material from different directions, and the second radiances may be measured at different positions around the material. The structure of the material could be determined by determining at least one of a scattering profile and an absorption profile. If the material includes a sheet of paper, a boundary between two layers in the sheet of paper could be identified by a discontinuity in the scattering profile, and a non-uniform distribution of a filler in the sheet of paper could be identified by a smooth variation in the scattering profile.
