Course Instructor

SC087: Optical Document Security

This course gives an overview of a wide variety of optical security features ranging from classic optically invariable devices, such as watermarks and intaglio printing, via tilt images, fluorescence and digital anti-copy devices to optically variable devices, based on diffraction and interference. Their basic physical principles are treated and their first and second line inspection properties are discussed. Genuine and counterfeit documents will be used as illustrations.
