Abstract

Le vérificateur optique de pièces de monnaie comprend une source de rayonnement pour l'éclairement de l'echantillon (pièce de monnaie à vérifier), M' un élément optique H', et un récepteur de rayonnement P. Dans l'élément optique H' sont introduites sous la forme de moyens de déviation de faisceau des informations relatives à la distribution spatiale d'angles d'inclinaison du relief d'une pièce de monnaie de référence et ceci de telle manière que les rayons réfléchis sur l'échantillon M' convergent en majeure partie vers la surface détectrice du récepteur de rayonnement P lorsque la distribution spatiale des angles d'inclinaison du relief de l'échantillon concorde avec celle de la pièce de monnaie de référence. Application notamment aux distributeurs automatiques.The optical coin verifier comprises a radiation source for illuminating the sample (coin to be checked), M 'an optical element H', and a radiation receiver P. In the optical element H ' information relating to the spatial distribution of angles of inclination of the relief of a reference coin is introduced in the form of beam deflection means, in such a way that the rays reflected on the sample M 'converge mostly to the detecting surface of the radiation receptor P when the spatial distribution of the angles of inclination of the relief of the sample matches that of the reference coin. Application in particular to automatic dispensers.
