AbstractThe rainbow hologram provides views of reconstruction with rainbow colorwithin a large viewing zone. In our recent paper, a Fourier rainbow holographicdisplay using diffraction grating and a white‐light LED source was introduced. Inthis technique, the rainbow effect is realized by the dispersion of white‐lightsource on diffraction grating, while the slit is implemented numerically by reduc-ing the demands of the space‐bandwidth product of the display. This paper pre-sents a novel analysis on the visual perception of the Fourier rainbow holographicdisplay using Wigner distribution. The view‐dependent appearance of the image,including multispectral field of view and viewing zone, is investigated consideringthe observer and the display parameters. The resolution of the holographic view isalso investigated. For this, a new quantitative assessment for image blur is intro-duced using Wigner distribution analysis. The analysis is supported with numeri-cal simulations and experimentally captured optical reconstructions for theholograms of the computer model and real object generated with different slitsize, reconstruction distance, and different observation conditions.
