We present experimental results obtained by a phase-shifting interferometer employing polarization capable of retrieve directional derivatives in $x$-direction (lateral shear). The system was adapted to obtain radial derivative (radial shear) and implemented with a cyclic interferometer with phase grid to multiplex the interference patterns. Using phase shifting by polarization, the interferometer is capable of processing the optical phase data with n-interferograms captured in a single shot. Experimental results are presented.
