A method for simultaneously measuring polarization and phase of arbitrarily polarized beams based on Pancharatnam-Berry phase

Based on the theory of the Pancharatnam-Berry phase, we propose a method for simultaneously measuring polarization and the phase of arbitrarily polarized beams by utilizing digital holography. This method requires merely a single-exposure imaging of interference fringes without changing any optical elements and thus greatly simplifies the operation of the measurement process. This method is more suitable for multiple measurements, especially for measuring the time-changing polarization. The conclusion is expected to provide a reference in polarization holography.
