Ghost imaging using two SPAD array detectors: a parameter study towards the realization of a 3D quantum microscope

Claudio Bruschini, Edoardo Charbon, Paul Mos, Yang Lin

Quantum ghost imaging can be an important tool in making optical measurements. One of the most useful aspects of ghost imaging is the unique ability to correlate two sets of independently collected information. We aim to use the principles of ghost imaging ...
