Abstract
Conventional dual-view integral imaging (II) three-dimensional (3D) display has the disadvantage of information halving in each viewing zone. We propose a holographic stereogram (HS) type dual-view 3D display without information halving in each viewing zone. The HS can be generated fast by Fourier transforming the elemental images of II into hologram elements (hogels). With shifted Fourier transform, each hogel is generated with a rotated viewing zone. By adjusting the viewing zone of each hogel to make them converge at a specific distance, a specific viewing zone is generated. Then, by adding the two holograms together, each of which corresponds to a separate viewing zone, a dual-view HS is obtained without halving the information presented in each viewing zone. The proposed method is verified through simulation and optical experiment.
