Quantum Imaging of an irregular array of Thermal Light Sources — •Anton Classen1, Raimund Schneider1,2, Thomas Mehringer1,2, and Joachim von Zanthier1,2 — 1Institut für Optik, Information und Photonik, Universität Erlangen-Nürnberg, 91058 Erlangen — 2Erlangen Graduate School in Advanced Optical Technologies (SAOT), Universität Erlangen-Nürnberg, 91052 Erlangen
Multiphoton interference of thermal light sources is a current topic of research [1,2]. Quantum imaging techniques based on multiphoton interference are able to beat the classical Abbe limit via post-selection [2]. So far this has been demonstrated for a setup with N equidistantly aligned thermal light sources and N detectors measuring the Nth-order correlation function. Here we present a more versatile detection scheme making use of arbitrary mth-order correlation functions to obtain structural information about irregular source geometries. We show that an unambiguous reconstruction of the entire source arrangement can be obtained in a sub-classical regime and present experimental results.
