Hc. Kandpal et E. Wolf, PARTIALLY COHERENT SOURCES WHICH GENERATE FAR FIELDS WITH THE SAME SPATIAL COHERENCE PROPERTIES, Optics communications, 110(3-4), 1994, pp. 255-258
A class of partially coherent model sources is described, which have d
ifferent distributions of the intensity and of the degree of spatial c
oherence, but which generate fields with the same coherence properties
throughout the far zone.
