Polarized single-scattering phase function determined for a common reflectance standard from bidirectional reflectance measurements

We report on Mueller matrix bidirectional reflectance distribution function (BRDF) measurements of a sintered polytetrafluoroethylene (PTFE) sample over the scattering hemisphere for incident angles from 0° to 75° and for four wavelengths from 351 nm to 1064 nm. The data are fit to a radiative transfer equation solution for a diffuse medium, letting parameters describing the single scattering phase function be adjusted.
