Webimages of the binary hologram is shown in Fig. 2b. It can be seen that the visual quality of the recon-structed image is favorable. To illustrate the effect of noise resistance on the binary hologram, about 20% of the binary pixels are randomly selected, and each of them is comple-mented, i.e., 1 s become 0 s and 0 s become 1 s. The WebNov 1, 1979 · Binary computer-generated holograms are similar to interferograms with fringe patterns hardclipped by a photographic process. Therefore the fringe locations in the binary hologram can be determined by solving a grating equation. However, there are two difficulties in using this approach to make binary Fourier transform holograms. d and j fabrics
