- Abstract
- We analyze the viewing angle of a holographic image reconstructed from the digital Fourier hologram with an enhanced numerical aperture (NA). The viewing angle of the reconstructed image depends on the NA of the digital hologram that is determined by a focal length of Fourier lens and hologram aperture size, which is irrespective of a location of imaging plane. The enhanced-NA digital hologram reconstructs the image with an angle larger than a diffraction angle of a hologram pixel. We also characterize the aliasing effect for this type of digital Fourier hologram, and find that the alias-free region exists even at a high numerical aperture. Numerical simulation and optical experiments are conducted to verify this interpretation of the viewing angle of holographic images.
