Coherence Poincaré Sphere
The classic Poincaré sphere construction is generalized from a single point to a pair of points within an optical beam, with the help of the Gram matrix. The generalized, coherence Poincaré sphere enables simultaneous characterization of the polarization properties of a beam at two positions while contains the information about the degree of coherence and the degree of cross-polarization in its radius. The properties of the coherence Poincaré sphere in the cases of uniform/non-uniform, complete/partial polarization are discussed separately. The numerical examples illustrating the sphere's application to the known partially coherent electromagnetic beams are provided.
