Paper Abstract

Authors design and manufacture a laser lithographic digital hologram using chaos theory and fractal images. The feature of the fractal image is presented. Fractals are a mathematical graph-object that is self-similar and chaotic. They have a special shapes, which show similar features at any different size. The another characteristic of the fractal images is divisible property infinitely besides their self-similar property. Authors introduce the fractal patterns to laser lithographic digital hologram for improvement and increase anti-counterfeiting function of the hologram. A laser lithographic digital hologram system is equipped with the fractal images at author's laboratory. The fractal digital embossing holograms are used to security and anticounterfeiting with success in the China.
