A micro-optic film structure that alone or together with a security document or label projects images spatially coordinated with static images and/or other projected images is provided. The inventive film structure is made up of: (a) one or more polymer film materials; (b) one or more planar arrangements of primary image icons; (c) one or more planar arrangements of focusing elements or lenses; and (d) one or more secondary image icons. The planar arrangements are configured such that when a planar arrangement of primary image icons is viewed through a planar arrangement of focusing elements or lenses, one or more first synthetic images are projected. The secondary image icons appear as static and/or other projected images. These images are spatially coordinated with the first synthetic image(s) projected by the film structure, such that when simultaneously displayed therewith, they visually enhance or cancel the projected first synthetic image(s).

A micro-optic film structure that alone or together with a security document or label projects images spatially coordinated with static images and/or other projected images

A tamper indicating optical security device that operates to produce one or more synthetic images is provided. Any attempt to detach (e.g., forcibly remove) this device from an underlying base material will cause one or more layers of the security device to separate or delaminate, rending the device partially or totally inoperable. The inventive device is contemplated for use with, among other things, currency or banknotes, secure documents such as bonds, checks, travelers checks, identification cards, lottery tickets, passports, postage stamps, and stock certificates, as well as non-secure documents such as stationery items and labels. The inventive device is also contemplated for use with consumer goods as well as bags or packaging used with consumer goods.

A tamper indicating optical security device

An optical device projecting one or more synthetically magnified images that has been laser marked with one or more static two dimensional (2D) images is provided. The static 2D image(s) laser marked on or within this device and the synthetically magnified image(s) projected by this device help determine the authenticity of a document (e.g., passport data page) or product that employs it. Several embodiments of the inventive device also offer increased resistance to tampering or alteration and wear.

A laser marked device

A system for projecting one or more synthetic optical images, which demonstrates improved resistance to optically degrading external effects, is provided. The inventive system serves to lock the focal length of the focusing elements in place. In other words, no other transparent materials or layers brought into contact with the inventive system will serve to materially alter the focal length or the optical acuity of synthetic images formed by the system.

An optical system demonstrating improved resistance to optically degrading external effects

An optionally transferable optical system with a reduced thickness is provided. The inventive optical system is basically made up of a synthetic image presentation system in which one or more arrangements of structured image icons are substantially in contact with, but not completely embedded within, one or more arrangements of focusing elements. The focusing element and image icon arrangements cooperate to form at least one synthetic image. By way of the subject invention, the requirement for an optical spacer to provide the necessary focal distance between the focusing elements and their associated image icon(s) is removed. As a result, overall system thicknesses are reduced, suitability as a surface-applied authentication system is enabled, and tamper resistance is improved.
