tabbs Posted June 18, 2005 Report Share Posted June 18, 2005 The Technical University Harburg (in Hamburg, Germany) has developed an optical sensor system that helps recognizing counterfeits. Current systems usually check features such as the size and weight of a coin, and the conductivity of the alloy. This sensor, developed for Crane NRI http://www.nri.de , can recognize photographic images and "wrong" relief structures. http://www.uni-protokolle.de/nachrichten/id/101588/ http://www.handelsblatt.com/pshb?fn=tt&sfn=go&id=1053938 (articles in German) Christian Quote Link to comment Share on other sites More sharing options...
