Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | In this paper, a comparative analysis of two approaches to synthesis 2D
hologram, which restores optical field without conjugated images, is performed. These
holograms are used in embossed rainbow protective holograms to improve their forgeryproof
characteristics. As a basis, one method of kinoform hologram synthesis is used,
which allows to obtain the restored image of acceptable quality, but phase-matching
condition is necessary to complete. That limits usage of this method in mass production
of embossed holograms. The offered method of combined holograms is based on
addition of optical fields restored by separated Fourier holograms. This method let us to
avoid hard requirements to technical process on resist – polymer relief translating
accuracy. Thus, the proposed method can be recommended for application in mass
production of rainbow protective holograms. |
