Short content of a presentation

The problem of creating of the light image with the specified parameters of quality holographic methods is concidered. The author developed a parallel supercomputer software package written in C++ , its functionality, scalability on cluster systems is described. The calculations were carried out on supercomputers MVS-100K MSC RAS and MIET T4700 . The results of calculations performed with the aid of this software, were used as in mathematical modeling, and for the manufacture of experimental holographic plates.

Described and implemented a special algorithm, which can calculate the field of 10^8-10^11 elementary objects on existing supercomputer systems. An example of calculation for the hologram image composed of 1.6*10^9 elements on a supercomputer MVS100 MSC RAS .

Describes various approaches to optimize the quality of the holographic image . The method of local variations applied to the problem of optimization of computer- synthesized hologram. It is shown that the optimization of the hologram can significantly decrease the effect Gibbs image .
