Abstract:
Ways and methods of modeling and calculating a holographic combiner for a virtual display are presented.  On the one hand, they allow Denisyuk holograms with high diffraction efficiency independent of the field angle to be generated. On the other hand, they allow the advantages of the holographic combiner when compared with a multilayer dielectric mirror to be maximally realized. Optimization and search of the design parameters of elements of an optical setup for generating an aspherical wavefront for recording a Denisyuk hologram are based on ray tracing. These processes are greatly facilitated by the use of an intermediate model in the form of a thin transparency for phase delay. The phase delay of this transparency, the mirror geometry of the optical setup that forms the aspherical wavefront for recording the hologram, and the actual model of Denisyuk hologram in this article are described in the form adopted in the Zemax environment for surfaces such as Binary1, Extended polynomial and Optically Fabricated Hologram.

Keywords:
