A light control material for displaying a color image. The light control material includes a material body including a plurality of microstructures. The microstructures are designed to produce an additive color perception of one or more colors and designed to reveal an image when the intensity of light reflected from a selected number of the microstructures is modulated. The selected microstructures can be modulated by one or more of modifying, obliterating, obscuring or covering up the selected microstructures. In one embodiment, the microstructures, prior to modulation of the selected number of microstructures, produce a uniform white additive color perception.

Light control material for displaying color, information, and images

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.

Optical system demonstrating improved resistance to optically degrading external effects

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.

Tamper indicating optical security device

A film material utilizing a regular two-dimensional array of non-cylindrical lenses to enlarge micro-images, called icons, to form a synthetically magnified image through the united performance of a multiplicity of individual lens/icon image systems. The synthetic magnification micro-optic system includes one or more optical spacers (), a micro-image formed of a periodic planar array of a plurality of image icons () having an axis of symmetry about at least one of its planar axes and positioned on or next to the optical spacer (), and a periodic planar array of image icon focusing elements () having an axis of symmetry about at least one of its planar axes, the axis of symmetry being the same planar axis as that of the micro-image planar array (). A number of distinctive visual effects, such as three-dimensional and motion effects, can be provided by the present system.

An 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.

A method for creating a master and for generating an optical waveguide therefrom. The method includes creating a waveguide master having the geometrical form of at least one optical element formed therein; and generating an embossed optical waveguide from the master, the embossed optical waveguide being a negative of the master, the embossed optical waveguide having an optical element formed therein which corresponds to and is a negative of the geometrical form of the optical element formed in the master, the embossed optical waveguide being formed of a polymer material having a first index of refraction, wherein the optical element is formed in the polymer material and creates a local modification of the refractive index of the polymer material.

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.
