OPTICAL SYSTEM FOR PROCESSING BANKNOTES USING RADIATION EMITTED BY PROTECTIVE ELEMENTS Russian patent published in 2007 - IPC G06K9/58 G07D7/06 

FIELD: engineering of devices for optical recognition of objects with optical encoding.

SUBSTANCE: in accordance to the invention, a banknote with light-active protective element is positioned along the transportation trajectory, irradiated by a source of stimulating effect and position of protective element is recognized by means of registration of radiation from protective element, excitation source is directed into detected location and protective element is irradiated, additional radiation from light-active protective element, received in response to light from excitation source, is registered. Recognition stage is realized using a camera with single row scanning, scanning axis of which is parallel or perpendicular to transpiration axis. Registered additional radiation may represent optical code for recognition of at least one special feature of a banknote.

EFFECT: ensured control over position and orientation of light-active materials, used in recognition process.
