Research on characteristics of partially coherent circularly polarized vortex beam in oceanic turbulence
The expression of partially coherent circularly polarized vortex beams (PCCPVBs) is introduced, and the matrix elements of a PCCPVB in oceanic turbulence are derived. The evolution of intensity and coherence of such PCCPVB is studied. The ring shape of a PCCPVB will gradually lose and become a spot pattern during propagation, and the PCCPVB with a smaller σ , and M will become a spot pattern more quickly. The intensity of a PCCPVB can show the flat profile when this PCCPVB propagates in free space, and the same PCCPVB in oceanic turbulence can show the Gaussian profile. The coherence of a PCCPVB in oceanic turbulence will decrease faster than the same PCCPVB in free space. The results may find application in underwater optical systems using circularly polarized beams.
