Invited Paper The Coherence of Multifrequency Optical Fields

摘要

An analysis of the generalized coherence of multifrequency optical fields is given, both in terms of observable quantities (coherence functions) and in terms of field quantities (analytical signal and amplitude spectral density of the field). The spectral structure of the generalized coherence function for a widespread class of multifrequency optical fields is given. Experimental results obtained by interferometrical investigation of the generalized coherence of such fields are presented.
