    "abstract": "We demonstrate experimentally and theoretically that a coherent image of a\npure phase object may be obtained by use of a spatially incoherent illumination\nbeam. This is accomplished by employing a two-beam source of entangled photons\ngenerated by spontaneous parametric down-conversion. Though each of the beams\nis, in and of itself, spatially incoherent, the pair of beams exhibits\nhigher-order inter-beam coherence. One of the beams probes the phase object\nwhile the other is scanned. The image is recorded by measuring the photon\ncoincidence rate using a photon-counting detector in each beam. Using a\nreflection configuration, we successfully imaged a phase object implemented by\na MEMS micro-mirror array. The experimental results are in accord with\ntheoretical predictions.",
