Abstract
Angular selectivity, where the geometry of the diffraction pattern depends on the incident direction of the readout beam, is observed in a computer-generated hologram synthesized with a photorefractive Fe-doped LiNbO3 single crystal. This angular selectivity is used to enhance the higher order diffraction patterns. Reconstruction of the strong second-order diffraction enables us to enlarge the effective reconstruction area of a Fourier-transformed computer-generated hologram.
