References(6) The studies of coherent optics such as optical spatial filtering, optical Fourier transformation, optical holography and its application techniques are now widespread according as the progress and diffusion of laser. On the other hand, many researchers have proposed the various simulation methods of coherent optics by means of the digital computer in stead of using the optical processing systems. In this paper, first of all the basic ideas and many parameters considered in generating the binary Fourier hologram by the computer are briefly reviewed. The authors examine the effect of quantization, in particular, the phase parameter which most influences visual appearance and blur of reconstruction image. Moreover, the results of the computer simulation are compared with that of the optically reconstructed image.
