Abstract
In recent years, topological singularities of wavefields have been considered as structures that can improve a variety of optical technologies, including remote sensing and free-space optical communications. However, atmospheric turbulence can distort the features of singularities over long propagation distances, limiting their use in many cases. One solution being considered is the reduction of spatial coherence of light, as partially coherent beams have shown increased resistance to turbulence under a broad range of situations. In this paper, we look at the evolution of polarization singularities that arise in a particular projection of a partially coherent vector beam, and how the position and number of singularities are affected by atmospheric turbulence. We find that there are projections where the singularities persist on propagation, suggesting their possible use in applications.
