We analyze the viewing angle of holographic image reconstructed from the digital Fourier hologram with an enhanced numerical aperture (NA). The viewing angle of reconstructed image depends on the NA of digital hologram that is determined by a focal length of Fourier lens and hologram size. The enhanced-NA digital hologram reconstructs the image with an angle larger than a diffraction angle of hologram pixel. We also characterize the aliasing effect of digital Fourier hologram, and find that the…

Wide viewing-angle holographic display based on enhanced-NA Fresnel hologram.

TLDR
It is found that the aliased replica noises generated in the enhanced-NA Fresnel diffraction regime are effectively suppressed within the diffraction scope by a digitized pixel, which enables the image reduction and to remove the interference of high-order images, which leads to the wide viewing-angle holographic display.
