Abstract

An interferometric method to measure the radial slope of dynamics transparent samples is presented. We have implemented a Simultaneous Phase Shifting Mach-Zehnder Radial-Shear interferometer(SPS-MZRI) using a phase grating to replicate the interference patterns and phase shifts modulated by polarization. The experimental results are presented in this work, as well as the experimental evidence for the generation of spiral patterns.
