HoloGen: An open-source toolbox for high-speed hologram generation

The rise of mixed reality systems such as Microsoft HoloLens has prompted an increase in interest the fields 2D and 3D holography. Already applied including telecommunications, imaging, projection, lithography, beam shaping optical tweezing, Computer Generated Holography (CGH) offers exciting approach to a wide range light problems. numerical processing required generate hologram is high requires significant domain expertise. This historically slowed adoption holographic techniques emerging fields. In this paper we present HoloGen, open-source Cuda C ++ framework for computer generated HoloGen unites, first time, array existing generation algorithms with state art performance while attempting remain intuitive easy use. enabled by # Windows Presentation Framework (WPF) graphical user interface (GUI). A novel reflection based parameter hierarchy used ensure ease modification. Extensive use templates on Standard Template Library (STL), compile time flexibility preserved maintaining runtime performance. current release unites implementations well known Gerchberg-Saxton (GS), Liu-Taghizadeh (LT), Direct Search (DS), Simulated Annealing (SA) One-Step Phase-Retrieval (OSPR) less specialist variants Weighted GS Adaptive OSPR. Benchmarking results are presented several key algorithms. software freely available under MIT license.
