Spatially varying polarization modulation with polarization singularities are realized using a birefringent wedge pair (BWP), which is due to coherent superposition of orthogonally polarized beams. We studied the degree of polarization, visibility and the degree of local coherence as a function of spatial coherence using Stokes polarimetric technique in and around the identified polarization singular patterns in the beam cross-section. Through these we illustrate the unification of coherence and polarization.
