Opto-electronic scanner for operational control of security holograms authenticity on documents

At present time, security holograms are widely used to protect against counterfeiting of various documents and identity cards. To control the security holograms authenticity on documents, devices that exclude the influence of the human factor and increase the speed and reliability of identification are needed. The paper presents an automatic optic-electronic scanner for operational control of security holograms authenticity on documents. The algorithm of data processing, operation principle of scanner and its design are described. The use of modern scanning systems, high-speed recording devices, specially designed and manufactured components of the optical system, as well as the use of correlation filters in the algorithm for recognizing the information received from the hologram, significantly reduce the time and raise the reliability of the security holograms authenticity control process.
