Paper Abstract

A new method is proposed for determining the coherence properties of the wave fields, produced by a broadband source, from the spectral changes produced an interference. The knowledge of spectral degree of coherence obtained experimentally combined with the space-frequency equivalence principle is used to determine the angular diameters of stars which is the source of the field. This is the first experiment which shows the application of spatial coherence spectroscopy in astronomy.
