Spanish Ministerio de Economía y Competitividad Project No.FIS2016-75199-PWe present an intuitive model of detector self-tomography. Two identical realizations of the detector are illuminated by an entangled state that connects the joint statistics in a way in which each detector sees the other as a kind of mirror reflection. A suitable analysis of the statistics reveals the possibility of fully characterizing the detector. We apply this idea to Bell-type experiments, revealing their nonclassical nature.engjournal articlehttp://dx.doi.org/10.1364/OL.410265https://www.osapublishing.orgopen access535OpticsÓptica (Física)2209.19 Óptica Física
