Equalizing S & P Reflected Polarization

Any arbitrary polarization component can be broken into equivalent S & P components. With complimentary sampling surfaces, any given component gets reflected once as the S polarization, and the second time as the P polarization. Thus using 2 surfaces, the total reflected energy for all polarization components is the sum of the S reflectance and the P reflectance. This causes the sampled beam to have S & P components that are identical to the original beam.
