Polarization is a useful quantity in understanding optical data. However, it is also one of the least understood quantities in remote sensing of granular media, and knowledge is particularly sparse in the area of hyperspectral data. There particularly have been few studies of the negative branch of polarization and these models have had limited success in describing observation. This thesis reviews previous studies of both positive and negative polarization by Hapke, Shkuratov, and others, presents experimental results taken in the Rochester Institute of Technology’s GRIT laboratory, and describes plans for future research to understand and model polarization. Experimentation described in this thesis shows a relationship between polarization and grain size, as well as a clear wavelength dependence.
