Fourier Rainbow Holography

We present Fourier rainbow holographic imaging approach. It involves standard laser holographic recording and novel horizontal parallax only holographic display. In the display, the rainbow effect is introduced in an illumination module by high frequency diffraction grating and white light LED source. The display is addressed by Fourier Rainbow Digital Hologram (FRDH) encoding defocused object field with removed spatial frequency components in one direction by hologram slitting and without spherical phase factor. Within the experiments it is shown that the method extends viewing zone of the classical viewing window display in the vertical and longitudinal directions, thus the comfort of observation is improved. It is also experimentally validated that the numerical slitting applied within FRDH generation can extend reconstruction depth of the display, here up to 400 mm.
