Abstract:
1. An optically variable device comprising: an array of focusing elements combined with a data-bearing volume containing visual data elements, wherein said visual data elements are contained within said volume and reflect or diffract light to create a virtual object array, wherein the virtual object array is disposed in a pre-determined virtual position located outside of said optically variable device at a distance spaced apart from the data-bearing volume, wherein the array of focusing elements provides a magnified view of said virtual object array, wherein when viewed from an observation point above the array of focusing elements, each of the array of focusing elements and the data-bearing volume is disposed between the virtual object array and the observation point, wherein between the array of focusing elements and the virtual object array, the optically variable device is devoid of images created by printing or surface relief, and wherein each virtual object in the virtual object array is disposed at a focal point of a corresponding focusing element of the array of focusing elements.
