SERRANO-GARCIA, D.I. et al. Simultaneous phase-shifting cyclic interferometer for generation of lateral and radial shear. Rev. mex. fis. [online]. 2011, vol.57, n.3, pp. 255-258. ISSN 0035-001X.
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.
