title: Reversing-wave-front interferometry of radiation from a diffusely illuminated phase grating.
abstract: Using a lateral-reversing-wave-front interferometer, we investigate the coherence of the radiation field emanating from a diffraction phase grating hidden behind a diffuser or illuminated by partially coherent light. We find further experimental evidence for a predicted coherence effect.
