Chapter 24 Toward 'Ghost Imaging' with Cosmic Ray Muons

摘要

Optical ghost imaging is a remote imaging technique that exploits either the correlations between light beams/entangled photon pairs, or the Hanbury-Brown Twiss [1, 2] effect typical of chaotic light sources. Is it possible to implement ghost imaging with massive particles? The Extreme Energy Events (EEE) project [3] offers a platform for attempting to answer this question. Our analysis is based on the experimental data taken in L'Aquila by two distant EEE muon telescopes [4, 5]. Interestingly, muons from cosmic ray showers exhibit spatio-temporal correlations that offer the possibility to evaluate the feasibility of ghost imaging with massive particle.
