- Аннотация: Nano-optical elements – a new breakthrough direction in security technology. Electron beam origination technology is used in production of originals of the nano-optical elements. The technology is well protected against counterfeiting or imitation by both the high price of E-beam equipment and complexity of the technology. E-beam technology offers a wide range of security features for visual control. DeColor effect is an example of such security feature based on asymmetrical micro-relief. The effect is easy for verification: from a normal viewing position an observer sees one image, but after rotation of an element through 180 degrees, an observer sees a different image in the same place. E-beam technology allows to make not only 2D, but also 3D visual effects. The vertical 3D/3D switch effect is an example of such security feature. The security feature consists in the alternation of two 3D color images when the diffractive element is tilted up/down. The switch effect can be observed under white light. E-beam technology allows to create CLR (Covert Laser-Readable) images for automatic control. The handheld portable reader for automatic control allows reliable and quick verification of nano-optical elements. The optical elements created with E-beam technology can be replicated using standard equipment employed for manufacturing security holograms. The new optical security features for visual and instrumental control are safely protected against counterfeit and designed to protect banknotes, documents, ID cards, etc.
