Visual quality assessment of digital holograms is facing many challenges.Main difficulties are related to the limited spatial resolution and angularfield of view of holographic displays in combination with the complexity ofsteering and operating them for such tasks. Alternatively, non-holographicdisplays - and in particular light-field displays - can be utilized tovisualize the numerically reconstructed content of a digital hologram. However,their suitability as alternative for holographic displays has not beenvalidated. In this research, we have investigated this issue via a set ofcomprehensive experiments. We used Fourier holographic principle to acquire adiverse set of holograms, which were either computer-generated from pointclouds or optically recorded from real macroscopic objects. A final public dataset comprising 96 holograms was created using three compression methods whichencoded the holograms at four bit-depths. Three separate subjective-tests wereconducted using a holographic display, a light field display and a 2D display.For these subjective experiments, a double stimulus, multi-perspective,multi-depth subjective testing methodology was designed and implemented. Thetests show that the non-holographic displays indicate a higher sensitivity toartifacts than the holographic display, though at the same time it isdemonstrated they are highly correlated. This indicates that the numericallyreconstructed holograms rendered on a light field or 2D display have a highpredictive value for the perceived quality on holographic display.
