For digital Fresnel holograms, angular field of view follows the hologram's numerical aperture, so closer synthesis distances give wider views, with aliasing suppression required to exploit the effect.

Methods for extending viewing-angle of holographic image by using digital hologram with high numerical aperture
For digital Fresnel holograms, angular field of view follows the hologram's numerical aperture, so closer synthesis distances give wider views, with aliasing suppression required to exploit the effect.
