Description	Numerical models of holograms are available but their evaluation is a very computationally intensive task especially in case of holograms intended for a human viewer. This paper presents an acceleration algorithm for optical field synthesis, which is suitable for the reduced occlusion method of hologram synthesis. The acceleration uses an approximation that is designed for FPGA and therefore it mostly uses fixed-point numbers. The paper describes the approximation, its fixed-point modication and the resulting FPGA structure. The results presented in the paper show that the solution produces high-quality holograms in a signicantly reduced time due to an efficient FPGA implementation.
