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. WebJul 30, 2010 · Cable et al. [10] on binary Fourier holograms, and Nozaki and Chen [11] and Moreno et al. [12] on kino-form and detour phase holograms. Methods for gen-eration of a binary hologram in an iterative manner have been reported in [13–15]. A review of the binar-ization of holograms is given by Ferri [16].
