Study on object wavefront sensing in parallel phase-shifting camera with geometric phase lens
HOLOGRAPHY, DIFFRACTIVE OPTICS, AND APPLICATIONS XI(2021)
摘要
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.
