This comprises previous approaches to coherence between vectorial waves and restores the equivalence between correlation-based coherence and visibility.engjournal articlehttp://dx.doi.org/10.1364/JOSAA.27.001764https://www.osapublishing.org/open access535Complete electromagnetic coherenceSpace-frequency domainYoungs interference experimentUnitary transformationsMaximum visibilityFringe visibilityStokes parametersFieldsPolarizationContrastsÓptica (Física)2209.19 Óptica Física
