Abstract
Заявляемая в качестве изобретения микрооптическая система формирования визуальных изображений относится преимущественно к приспособлениям, используемым для удостоверения подлинности изделий, и может быть эффективно использована для защиты банкнот, ценных бумаг, документов, пластиковых карточек, банковских расчетных карточек, акцизных, идентификационных, контрольных марок, а также различных товаров народного потребления от подделки. Микрооптическая система согласно изобретению состоит из размещенного на плоской подложке однослойного плоского фазового оптического элемента, фазовая функция которого представляет собой сумму фазовой функции плоского оптического элемента, формирующего в фокальной плоскости заданное изображение, и фазовой функции внеосевой параболической линзы Френеля и/или линзы Френеля с седлообразной фазовой функцией, формирующего в рассеянном свете изображение с визуальным эффектом смещения при наклонах подложки относительно наблюдателя. Заявленная совокупность существенных признаков изобретения обеспечила достижение технического результата, заключающегося в повышении надежности визуального контроля защищаемых с его помощью изделий за счет получения легко контролируемого эффекта движения изображения, в уменьшении толщины микрооптической системы и расширении сферы ее применения. Реализация микрооптической системы формирования визуальных изображений возможна с использованием существующего стандартного оборудования.The micro-optic imaging system of the invention as claimed in the invention mainly relates to devices used to authenticate products, and can be effectively used to protect banknotes, securities, documents, plastic cards, bank payment cards, excise, identification, control marks, and various consumer goods from a fake. The micro-optical system according to the invention consists of a single-layer planar phase optical element placed on a flat substrate, the phase function of which is the sum of the phase function of the planar optical element forming a given image in the focal plane and the phase function of an off-axis parabolic Fresnel lens and / or a Fresnel lens with a saddle-shaped phase a function that forms an image in scattered light with a visual effect of displacement when the substrate is tilted relative to the observer. The claimed set of essential features of the invention has achieved the achievement of the technical result, which consists in increasing the reliability of the visual control of the products protected with it by obtaining an easily controlled effect of image movement, reducing the thickness of the micro-optical system and expanding its scope. The implementation of a micro-optical imaging system is possible using existing standard equipment.
