Abstract

Подложка для создания, по меньшей мере, одного оптически изменяющегося изображения содержит множество групп элементарных областей, причем различные группы формируют соответствующие пикселы изображения. Различные элементарные области (А-A) содержат соответствующие канавки или выступы или множества канавок или выступов (12-12), которые имеют различную ориентацию в различных элементарных областях, так что каждая элементарная область каждого пиксела направляет свет наблюдателю при соответствующем угле наблюдения. Для любого заданного угла наблюдения изображение, видимое наблюдателю, создается светом, отраженным или преломленным соответствующими элементарными областями каждого пиксела, без интерференции света от различных пикселов.Международная заявка была опубликована вместе с отчетом о международном поиске.
