Sorted by: 1. The most accurate way to do this simply would be to use the Brewster angle. You set up your sample with a laser that is polarized perpendicular to the surface; then you measure the reflection as a function of angle of incidence. You get a clear null in the reflection at just one angle - the Brewster angle.
