The space-shift-variant two-point correlation function of a transversely spatially localized optical field of arbitrary coherence at a remote plane is measured with a novel interferometric technique. The method permits reconstruction of the correlation function by a simple resorting of the measured data. In the case of a coherent field the experimentally measured correlation function is shown to factorize, as expected, and the field amplitude and phase are also reconstructed.

  11. If the shear is not introduced in the object space of the imaging system, then the interferograms exhibit tiltlike fringes perpendicular to the direction of shear that arise from the spherical phase front that is imposed upon the field by the lenses.
