摘要

The properties of periodicity and linear separation/combination of optical retardation are adopted to develop the Random-Retardation-Encoding anti-counterfeiting technology. In the experiments of this paper, the authentication pattern was divided into two parts with different random retardation distribution. The two parts of random retardation pattern were fabricated on two separate films. One of them can be used as the authentication tag, and the other is used for the identification of the authentication tag. Because the resolution of the random retardation pattern can be made very high, it's very hard to counterfeit the authentication tag without knowing the original design pattern. In addition, the transparency property of the retardation film makes it easy to be integrated with other anti-counterfeiting method, e.g. it can be laminated on a hologram without destroying the visual performance of the hologram while the authentication function of the retardation film is still maintained.
