Intensity Interferometry in the Spatial Domain

Abstract

A modification of the Hanbury Brown-Twiss experiment is described whereby intensity correlation is performed using coherent light and the statistical averages are taken in the space domain. This result is used to reconstruct the irradiance distribution of a spatially rough source. The far- field intensity distribution is recorded spatially for one time-resolution unit of the detector. The resulting spatial signal is autocorrelated and related to the intensity distribution over the source. Thus, without averaging in the time domain, a spatial Fourier-transform relation is derived between the far-field intensity correlation and the source irradiance, similar to the results of Hanbury Brown and Twiss.
