Research and development in the field of physical realization of optical structures based on the principle of diffractive optics by means of electron beam lithography in a recording material supported by a silicon or glass board. The research covers the analysis of the optical motive, research and application of relief structures implementing the required optical properties, research and modeling of the physical possibilities of implementation of relief structures, preparation and analysis of technology of implementation of relief structures with regard to the limits of current scientific instruments, verification of theoretical considerations by means of relief structure sample exposure
