title: Characterization and reconstruction of planar sources that generate identical intensity distributions in the Fraunhofer zone.
abstract: A general explicit form of the correlation functions of all the partially coherent quasi-monochromatic sources that generate identical intensity distributions at the far (Fraunhofer) zone is given. The common characteristic part of all of these correlation functions is pointed out. Also, the possibility is shown for reconstructing (in unique way), from intensity data at the far zone, any source whose correlation function at some region Omega depends on the coordinate difference only.
