FFT Implementation for Electronic Holograms using Field Programmable Gate Array

The majority of holograms are made using interference of light and computer-generated holograms. In this work we propose a real time FFT implementation to generate Fourier holograms with a VLSI digital component. Nowadays digital designers are increasingly using field programmable gate arrays (FPGAs), powerful hardware devices combining the main advantages of ASICs and DSPs with the possibility of re-programming, which make them very attractive devices for rapid prototyping. This paper also shows how the Xilinx system generator (XSG) environment can be used to develop hardware-based computer FFT algorithm from a system level approach, which makes it suitable for developing co-design environments
