Abstract
An optical device () for providing a synthetic integral image includes a polymer foil stack (). The polymer foil stack () includes at least one polymer foil (). A first interface () of the polymer foil stack () includes optically distinguishable image data bearer structures (). The first interface () has a general shape defined by a first array () of curved interface portions (), on which the image data bearer structures () are superimposed. Preferably, the optical device () includes a second interface () of the polymer foil stack (), which has a second array () of microlenses (). The second interface () is provided at a distance from the first interface (), which distance is close to a focal length of the microlenses (). The second array () is in registry with the first array ().
