Integral Lens Array Imaging as an Anti-Counterfeit Marker
University of Kentucky The goal of this project is to develop an inexpensive means of manufacturing holographic display devices as a security marker. Holograms, like the ones being proposed here, have long been used to protect hard copy documents such as security certificates, credit cards, or identification cards like a drivers license. In fact, the U.S. Treasurer has just announced the use of holographic devices on its new $100 bills, which use a lens-based technology similar to the technology that we are proposing. In this project, we will develop the imaging process for forming the hologram, which will include an optics system composed of an off-the-shelf DLP projector for projecting the desired holographic image onto the first side of a plastic lens array, back-coated with a light sensitive material layer. The active digital panel will allow for varying the provided image to create a three dimensional image and to account for distortions caused by the optics system or curvature in the integral lens array and light sensitive material.
