Classification of the coherence in multipath interference patterns — •Kai von Prillwitz, Łukasz Rudnicki, and Florian Mintert — Freiburg Institute for Advanced Studies, Albert-Ludwigs University of Freiburg, Freiburg 79104, Germany

In multipath experiments the contrast of the interference pattern depends strongly on the number of coherently interfering path alternatives, and the contrast decreases with increasing decoherence. We show how to infer the number of interfering paths from the statistical moments of the interference patterns, and demonstrate that a few moments are enough information to obtain a reliable characterization of coherence properties.
