Paper Abstract

It is offered to use the methods of the optical superresolution based on the redistribution of spatial, temporal and polarization degrees of freedom of the optical image conception for the holograms protection against a falcification. On an example of optical synthesis of the aperture (OSA) at recording of the Fourier holograms the principles and possibilities superresolving methods of coding are discussed. The peculiarities of the method OSA associated with appearances of the self-image of periodic coherent fields (Talbot's effect) are considered.
