Abstract
A synthetic micro-optic system and security device is disclosed including an in-plane image formed of an array or pattern of image icons and an array of focusing elements, the system producing at least two different synthetic images whereby one synthetic image operates to modulate or control the extent of the appearance of another synthetic image. In an exemplary form, the array of image icons forms an in-plane synthetic image, while the interaction of the array of focusing elements with the array of image icons forms a separate synthetically magnified image that serves to control the field of view of the in-plane image and, thus, serves to modulate or control the extent of appearance of the in-plane image. The appearance of the in-plane image, thus, visually appears and disappears, or turn on and off, depending upon the viewing angle of the system.
