Abstract

A polarizing holographic system of protection contains a polarization-holographic protective element, on which the code is recorded, and the device identifying this code. A code recording on the protective element occurs by polarization-holographic method in the form of one concrete combination of polarization position of two recording beams, which are preliminary selected from the big set of combinations of polarization conditions. The polarization-sensitive materials received under certain technology are applied to record the code on the protective element. These materials are made in such a manner that they have the precise and preliminary defined values of reactions with respect to polarizing light. Authenticity of a protective element is established by the identifying device. The basic analyzing detail of this device is represented by the polarization-holographic element, which is capable to spend the complete analysis of the condition of polarization of light falling on it and diffracted on the protective element in the real-time mode. The device automatically compares the received values of the certain parameters to the standard, which is stored in memory of the device comparison block. Fig: 2
