Radial slope measurements of transparent samples using phase shifting interferometry by polarization

Abstract

We present experimental results obtained by using phase-shifting interferometry by polarization to measure the radial slope of transparent samples, by implementing a Radial-Shear interferometer and using a grating to replicate the interference patterns modulated by polarization; the interferometer is capable to process the optical phase data by obtaining four interferograms in one-shot. The experimental results for transparent samples are presented in this research.
