A security device includes an image projection system that includes an array of focusing elements (101) and an array of image icon elements (103) disposed relative to each other such that a synthetic image is projected by the image projection system. This synthetic image, along with at least one other image functions as a targeting image. As targeting images (310′, 310″), these images are spatially coordinated such that a reward image (350), which is otherwise at least partially hidden, becomes revealed upon the targeting images having a predetermined transformation. This targeting effect functions as a game that attracts the attention of an end-user of high-valued articles of manufacture to which the security device is attached. The security device allows a viewer to actively interact with the security device by trying to turn on the reward image.

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.
Am image presentation system employing microstructured icon elements to form an image. In one form a synthetic optical image system is provided that includes an array of focusing elements, and an image system that includes or is formed from an array or pattern of microstructured icon elements, such as those described below, wherein the microstructured icon elements are designed to collectively form an image or certain desired information, and wherein the array of focusing elements and the image system cooperate, for example through optical coupling, to form a synthetic optical image which image may optionally be magnified. In another form an image presentation system is provided that includes or is formed from an array or pattern of microstructured icon elements, such as those described below, wherein the microstructured icon elements are designed to collectively form an image or certain selected information, and wherein the image system is designed to stand alone and be the image viewed or the information read by use of a magnifying device, such as a magnifying glass or microscope, that is provided separately from the image system.
G02B 30/27 - Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images by providing first and second parallax images to an observer’s left and right eyes of the autostereoscopic type involving lenticular arrays
