Accelerating digital hologram generation

Popis výsledku v původním jazyce

We see the real world through reflected light. The hologram is a recording of such light and it offers reproduction that is not distinguishable from the reality. Since we known a numerical approximation of the hologram, we can display virtual scene through it. However, hologram calculation is a time extensive process. Therefore, we accelerate calculation of large holograms intended for viewing purposes. Being inspired by the computer graphics, we reduce the detail of the scene by converting it to uniform elements. The method combines two different trends of hologram generation. We apply propagation of the angular spectrum to process the elements but we also apply ray-casting to solve visibility. We show that this combination is possible and it offers opportunities for further acceleration. The resulting method is not the fastest in a general case but we show that it is satisfactory for usual scenes. Besides the new method, we also discuss acceleration of another existing approach that
