Abstract

Digital pixel holography on the basis of scalar diffraction theory has an effective security function in anti- counterfeiting technology. The digital pixel hologram is in reality a diffraction element. The digital pixel hologram is a laser lithographic image to produce high efficiency volume phase only computer generated holographic diffraction grating. The use of the Postscript language program and the chaos fractal patterns generating program as an interface between the mathematical coding and the laser lithographic device is effective, since this model has flexible and powerful security function for anti-counterfeiting technology. The Postscript files and chaos fractal patterns generating program can control the lithographic system which has a Postscript and chaos fractal patterns generating interpreter.
