There is an implicit assumption in all of spectroscopy that the relative energy distribution in the spectrum of radiation which propagates in free space is independent of the location of the observer, provided that the observer and the source are at rest relative to each other. That this assumption is not valid, in general, was suggested by the results of an investigation of Mandel111, carried out almost thirty years ago. Mandel showed that when light beams from two small correlated sources which have the same normalized spectra are superposed, the normalized spectrum in the region of superposition will differ, in general, from the normalized spectrum of each source. More recently it was predicted theoretically2 and confirmed experimentally soon therwards3 that the normalized spectrum of light produced by an extended source, will, in general, differ from the normalized source spectrum (assumed to be the same at every source point); and that it will depend on the location of the point of observation. The spectral changes were shown to depend on the correlation properties of the source.
