Experimental study of coherence vortices: Local properties of phase singularities in a spatial coherence function
By controlling the irradiance of an extended quasimonochromatic, spatially incoherent source, an optical field is generated that exhibits spatial coherence with phase singularities, called coherence vortices. A simple optical geometry for direct visualization of coherence vortices is proposed, and the local properties and the spatial evolution of coherence vortex are experimentally investigated.
To our knowledge, this is the first direct and quantitative experimental measurement of a generic coherence vortex.
