Radially polarized (RP) beam with controllable spatial coherence (i.e., partially coherent RP beam) was generated in experiment recently [Appl. Phys. Lett. 100, 051108 (2012)]. In this letter, we report experimental study of the scintillation index of a partially coherent RP beam propagating through thermally induced turbulence. Our results show that a partially coherent RP beam has advantage over a linearly polarized partially coherent beam for reducing turbulence-induced scintillation, which will be useful in free-space optical communications, remote sensing and laser radar systems.
