The generation and propagation of a Besinc-correlated partially coherent vortex beam (BS-PCV beam) have been investigated. Based on the van Cittert–Zernike Principle, the spatial coherence distribution of the light beams, which radiated from the controllable annular extended incoherent light source is studied theoretically. The theoretical calculations show that, the spatial coherence of the light beams which radiate from controllable annular extended incoherent light source changes into partial coherence after propagation. Moreover, the spatial coherence of the light beams is Besinc-correlation. Experimentally, A BS-PCV beam with controllable spatial coherence is generated by using an annular extended incoherent light source and a spiral phase plate. Furthermore, by use of the double-slit interference the topology charge number is measured. Additionally, the propagation of BS-PCV beams in a free space is investigated based on extended Huygens-Fresnel Principle. The influence of the controllable spatial coherence on the propagation is investigated.
