Abstract
The numerical modeling of light propagation based on Fresnel wavefront decomposition was performed. The reconstruction of a wavefront based on the direct superposition of Fresnel-Kirchhoff modifoed Greens functions was implemented. The high flexibility of possible initial conditions of simulation was applied for the calculation of holograms. The problems of fabrications of numerical simulated holograms was analyzed. The applicability of two-beam based material structuring equipment was analyzed. The method for decomposition of digital holograms into periodical two-beam interference pattern was researched. Based on this method, the group of producible holographic structures was found. The implementation of this model for numerical calculations of pattern decomposition was done. The transformation of estimated elements of decomposition was transformed into package of parameter for two-beam interference material structuring equipment.
