OPTICALLY-BASED SYSTEM FOR PROCESSING BANKNOTES BASED ON SECURITY FEATURE EMISSIONS

摘要

A method and a system are disclosed for processing a banknote.(30). The method includes providing a banknote (30) having at least one photonically active security feature (50), the banknote (30) being moved along a conveyance path; illuminating the at least one security feature (50) with light (60) from a stimulus source (58); identifying a location of the at least one security feature (50) by detecting an emission (62) from the security feature; directing an excitation source (52) at the identified location; illuminating the at least security feature with light from the excitation source (52); and detecting a further emission from the photonically active security feature in response to the light from the excitation source.
