"A problem of synthesis of nano-optical elements for the formation of dynamic images"
Goncharsky A.A., Durlevich S.R.

The inverse problems of synthesis of nano-optical elements for the formation of dynamic images that change their position as the flat optical element is tilted are considered. The inverse problem of computing the microrelief of nano-optical elements is solved in the framework of the Fresnel scalar wave model. The microrelief is formed using the electron-beam lithographic technology. Nano-optical elements with dynamic effects are used to protect documents against counterfeiting.

Keywords: nano-optical elements, flat computer optics, electron beam lithography, inverse problems, computer generated hologram, protection against counterfeiting
