Abstract
Заявляемое изобретение относится преимущественно к технологиям, используемым для удостоверения подлинности банкнот. Изобретение обеспечивает как визуальный, так и автоматизированный контроль оптических защитных меток на банкнотных нитях. Согласно заявляемому изобретению оптическая защитная метка представляет собой плоский оптический элемент, который содержит элементарные области R, j=1...m, размер которых не превосходит 50 мкм, в каждой из областей Rсформированы киноформы с асимметричным микрорельефом, которые при освещении оптической защитной метки лазерным излучением формируют в фокальной плоскости, параллельной плоскости купюры, двумерное асимметричное относительно нулевого порядка дифракции изображение, состоящее из однородных областей одинаковой яркости, а остальная часть оптической защитной метки полностью или частично заполнена дифракционными решётками. Для автоматизированного контроля осуществляют сканирование лазерным лучом, перпендикулярным плоскости купюры, вдоль всей банкнотной нити. Защитная нить признаётся подлинной, если изображения, формируемые в фокальной плоскости в процессе лазерного сканирования каждой из видимых частей банкнотной нити, совпадают с эталонным изображением. Визуальный контроль осуществляют при освещении банкнотной нити белым светом. Предложен вариант устройства для автоматизированного контроля подлинности оптических защитных меток.The invention relates primarily to the technologies used to authenticate banknotes. The invention provides both visual and automated control of optical security marks on banknote threads. According to the claimed invention, an optical security label is a flat optical element that contains elementary regions R, j = 1 ... m, the size of which does not exceed 50 microns, in each of the regions R are formed kinoforms with an asymmetric microrelief that radiation form in the focal plane parallel to the plane of the bill, two-dimensional asymmetric about the zero order of diffraction image consisting of homogeneous areas of the same brightness, and the rest The second part of the optical watermark is fully or partially filled with diffraction gratings. For automated control, a laser beam, perpendicular to the plane of the bill, is scanned along the entire banknote thread. The security thread is recognized as genuine if the images formed in the focal plane during the laser scanning of each of the visible parts of the banknote thread coincide with the reference image. Visual inspection is carried out with the illumination of a banknote with white light. A version of the device for automated control of the authenticity of optical security labels is proposed.
