CA 2179994

Detecting counterfeit banknotes is achieved by directing ultraviolet light at a sample from a source (104) and measuring the level of ultraviolet light reflected from the sample using a first photocell (105) and the amount of fluorescent light generated by the sample using a second photocell (106). The detected levels are compared with reference levels and only if both reflective and fluorescent criteria are satisfied is the note declared genuine. The sample, during test, is swiped over a glass window (102), preferably under an overlying shield.

Selon l'invention, on peut détecter des faux billets de banque en dirigeant sur un échantillon une lumière ultraviolette provenant d'une source (104) et en mesurant le niveau de lumière ultraviolette réfléchie par l'échantillon à l'aide d'une première cellule photoélectrique (105), ainsi que la quantité de lumière fluorescente générée par cet échantillon à l'aide d'une seconde cellule photoélectrique (106). On compare ensuite les niveaux détectés avec des niveaux de référence et le billet n'est déclaré authentique que si les deux critères de réflexion et de fluorescence sont réunis. Lors du test, on fait passer l'échantillon sur une vitre en verre (102) et de préférence sous un écran protecteur.
