Abstract
Security holograms are widely used for anti-counterfeiting of banknotes, documents and consumer products. The development of automated devices for operative authentication and quality inspection of security holograms is still an actual task. There are several approaches to solving this problem. One of them is based on an image comparison of inspected and reference holograms. Also for quality inspection of security holograms, the methods based on direct and indirect measurements of microrelief parameters are used. In this article we present a complex solution for automated quality inspection and authentication of security holograms.
