KSEF RDE: Integral Lens Array Imaging as an Anti-Counterfeit Marker

The goal of this project is to develop an inexpensive means of manufacturing holographic display deviccs as a security markcr. Holograms, like the ones being proposed herc, have long been used to protect hard copy documents such as security certi ficates, crcdit cards, or identification cards like a drivers liccnse. In fact, the U.S. Treasurer has just announced the usc of holob'Taphic devices on its new SI00 bills. which use a lens-based technology similar to the technology that we are proposing. Having such devices printed onto the surface of medicinal tables, at a per tablet cost of less than $0.05, would similarly secure our nation's drug supply. So in this project, we will develop the imaging process for forming the hologram, which will include an optics system composcd of an off-the-shelfDLP projector for projecting the desired holographic image onto the first side of an integral lens array where the integral lens array has a light sensitive material layer spaced relative to the second side of the integral lens array. The active digital mask 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 integrallcns array and light sensitive material.
