RT Journal Article T1 Partially coherent sources with circular coherence A1 Santarsiero, Massimo A1 Martínez Herrero, Rosario A1 Maluenda, David A1 González de Sande, Juan Carlos A1 Piquero Sanz, Gemma María A1 Gori, Franco AB A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence can be partial or even vanishing. Such sources can be synthesized by using a generalized form of van Cittert Zernike theorem where axial sources are used. Beams radiated by this type of source are analyzed at the source plane and upon free propagation for some simple cases.
