title: Quantum imaging of nonlocal spatial correlations induced by orbital angular momentum.
abstract: Through scanned coincidence counting, we probe the quantum image produced by parametric down-conversion with a pump-beam carrying orbital angular momentum. Nonlocal spatial correlations are manifested through splitting of the coincidence spot into two.
