Abstract
We derive expressions for the far-zone correlation of intensity fluctuations (the Hanbury Brown-Twiss effect) that occurs in electromagnetic beams that are generated by quasi-homogeneous sources. Such sources often have a radiant intensity pattern that is rotationally symmetric, irrespective of the source shape. We demonstrate how from the far-zone correlation of intensity fluctuations the spectral density distribution across the source plane may be reconstructed.
