Abstract

Защитное устройство содержит подложку (1), имеющую решетку микролинз (3) на одной стороне и одну или более решеток микроизображений (4) на другой стороне. Микроизображения (4) размещены на расстоянии от микролинз (3), практически равном фокусному расстоянию микролинз. Подложка (1) в достаточной степени прозрачна, чтобы давать возможность свету проходить через микролинзы (3), с тем, чтобы достигать микроизображений (4). Каждое микроизображение (4) задается посредством просветляющей структуры на подложке (1), сформированной посредством периодической решетки идентичных структурных элементов, причем свет, проходящий через подложку и падающий на микроизображения, отражается в другой степени, чем свет, который не падает на микроизображения, тем самым, воспроизводя микроизображения видимыми.
