Measurement of surface form error of an optical surface with reduced interferometric spatial coherence artifacts using a ring source and polarization phase-shifting interferometry.
TL;DR: A technique for the measurement of surface form error of an optical surface using a ring source and polarization phase-shifting interferometry (PPSI) and the main advantage is that the perturbations in the Fizeau cavity are negligible during the phase shifts.
