WebJan 3, 2024 · Effects of Under Sampling (Aliasing) The sampling rate is very low. The signal is not band-limited to a finite range. WebAbstract: This letter discusses an aliasing effect which has caused anomalous behavior in some recent experiments with coarsely sampled holograms. Aliasing occurs because the sampling criterion is not satisfied over the full aperture of the hologram. The result is the appearance of ghost zone patterns on the hologram which can degrade the reconstructed …
