  We present the experimental characterization of two distant double-slit masks
illuminated by chaotic light, in the absence of first-order imaging and
interference. The scheme exploits second-order interference of light
propagating through two indistinguishable pairs of {\it disjoint} optical paths
passing through the masks of interest. The proposed technique leads to a deeper
understanding of biphoton interference and coherence, and opens the way to the
development of novel schemes for retrieving information on the relative
position and the spatial structure of distant objects, which is of interest in
remote sensing, biomedical imaging, as well as monitoring of laser ablation,
when first-order imaging and interference are not feasible.
