Study on object wavefront sensing in parallel phase-shifting camera with geometric phase lens

In this paper, we present the result of our study on the development of the digital holographic microscope with a geometric phase lens and the parallel phase-shifting polarization camera. In numerical simulation and the experiment, it was shown that in this configuration, the geometric phase lens leads to a shear interference pattern formation, thus causing a overlapping diffraction orders in the reconstructed image and additional modulating phase term. Possible strategies to compensate this phase term are discussed.
