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