Minimization of reconstruction errors with computer generated binary holograms

Generation of holograms by computer allows the possibility of better controlling the hologram formation process and of displaying a synthesized image in the case where the object does not exist physically. However, limitations of equipment used to plot the hologram can cause degradation of the reconstructed image. We examine these degradations for the binary Fourier transform hologram and present a method by which the plotting procedure may be designed so as to yield a most faithful reconstructed image. Experimental results which support the analysis are included.
