Abstract

One method of generating synthetic or computer generated holograms is to first compute the Discrete Fourier Transform (DFT) of the desired image. The hologram is then formed by coding in some manner on photographic film the complex values of this DFT. This paper will describe a method for generating synthetic binary holograms that avoids completely the necessity for computing the DFT of the desired image. The relationship between this new method and previously used techniques will be explored.
