TLDR
In this article, the authors provide methods and compositions for identification and counterfit deterrence using non-holographic micro-optics and microstructures having a surface relief greater than a few microns.Abstract:
The present invention provides methods and compositions for identification and counterfit deterrence using non-holographic micro-optics and microstructures having a surface relief greater than a few microns. Embodiments of the present invention disclose a range of distinctive optical effects obtained from micro-optic systems incorporating micro lenses (35), non-imaging collectors (31), prisms, wave guides, mirrors (68), gratings, structural interference filters, and photonic crystal microstructures.read more

Patent
Micro-optic security and image presentation system
TL;DR: In this paper, an in-plane image consisting of an array or pattern of image icons and an array of focusing elements is presented, where the interaction of the focusing elements with the image icons forms a separate synthetically magnified image that serves to control the field of view of the inplane image and, thus, serves to modulate or control the extent of appearance of the image.
Patent
Security element and method for the production thereof
TL;DR: In this paper, a security element for protecting valuable objects having first and second authentication features is proposed, where the first authentication feature consists of a plurality of focussing components arranged in a first raster and a second arrangement consisting of plurality of microscopic structures arranged in the second raster.
Patent
Sheeting with composite image that floats
TL;DR: Translucent, transparent, or semi-translucent microlens sheetings with composite images are disclosed, in which a composite image floats above or below the sheeting, or both as discussed by the authors.
Patent
Image presentation and micro-optic security system
TL;DR: In this paper, an image presentation system employing microstructured icon elements to form an image is presented, where the image system is designed to stand alone and be the image viewed or the information read by use of a magnifying device.
Patent
Method and apparatus for drug product tracking using encoded optical identification elements
TL;DR: In this paper, a method and apparatus for drug product tracking (or other pharmaceutical, health care or cosmetics products, and/or the packages or containers they are supplied with) using diffraction grating-based encoded optical identification elements (8) includes an optical substrate (10) having at least one diffraction GRating (12) disposed therein.
