Viewing angle analysis of reconstructed image from digital Fresnel hologram with enhanced numerical aperture
Byung Gyu Chae
The viewing-angle enlargement of a holographic image is a crucial factor for realizing the holographic display. The numerical aperture (NA) of digital hologram other than a pixel s…

Analysis on image recovery for digital Fresnel hologram with aliased fringe generated from self-similarity of point spread function
Byung Gyu Chae
We analyze the aliasing phenomenon for digital Fresnel hologram with an enhanced numerical aperture (NA). The enhanced-NA digital hologram acquired computationally or optically at…

Methods for extending viewing-angle of holographic image by using digital hologram with high numerical aperture
Byung Gyu Chae
We investigate the angular field of view (AFOV) of a holographic image reconstructed from the digital Fresnel hologram in holographic display. The theoretical analysis reveals that…
